Previously, if a property name had successive capital letters, the
generated meta-data would clean it in such a way it is defined as a
regular word. For instance a `myFOO` property would be written as
`my-foo` in the meta-data.
It turns out this decision is wrong as the binder has no way to compute
back the name of the property and therefore `my-foo` wouldn't bind to
`setMyFOO` as it should.
This commit updates the meta-data name generation algorithm to properly
identify such cases: `myFOO` now translates to `my-f-o-o`. While the
generated name is a bit ugly, it now provides a consistent binding
experience.

JarURLConnection is very performance sensitive. The change in 3772d9f
meant that every JarURLConnection would create a FilePermission,
irrespective of whether it was actually used.
This commit updates JarURLConnection to create its FilePermission
lazily. When there is no security manager a permission will no longer
be created at all.
Closes gh-5411
See gh-6215
In fact the folder was already created if the app is running as
a different user, but not if running as the current user, so it
was just a question of moving one line out of an if block.
Fixes gh-5986
Update TypeUtils to guard against the use of older Java versions.
Both `Collection` and `Map` type lookups now fallback to generic free
versions of the classes.
Prior to this commit using `xmlbeans-maven-plugin` in combination with
Spring Boot's annotation processor could result in
`IllegalArgumentException: Incorrect number of type arguments`.
Fixes gh-6122
Previously, JarURLConnection didn't override getPermission(). This
meant that it required all permissions. This was at odds with the
Oracle JVM's concrete sun.net.www.protocol.jar.JarURLConnection which
overrides getPermission to return a FilePermission with the read
action for the path of the underlying jar.
This commit updates our JarURLConnection to align its behaviour with
sun.net.www.protocol.jar.JarURLConnection.
Closes gh-5411
Previously, arguments passed to the script were handled in one way
if a service was being started using start-stop-daemon and in another
way if start-stop-daemon wasn’t available or the application is being
launched in run mode. This meant that quoted arguments were only
handled correctly when the application was being started using
start-stop-daemon.
This commit updates the launch script so that argument handling is
the same across all three different way that the application can be
launched.
Closes gh-5942
Using a separate thread to call the application's main method is
unnecessary – the context class loader of the current thread can be
updated instead – and makes exception and exit code handling more
complicated than it needs to be.
This commit updates the Launcher so that it calls the main method
runner using the current (main) thread. As a result, any exception
that's thrown will be caught by the JVM and result in a non-zero exit
code being returned from the process.
Closes gh-5922
Previously, if a void method with a single argument was named "set", the
annotation processor wrongly considered it was a setter candidate. This
commit updates the condition to ignore it.
Closes gh-5826
Previously, JarURLConnection would fail when created with a URL that
began with jar:file:// as the double-slash is not included in jarFile.getUrl().getFile().
This commit updates JarURLConnection to normalise the value return from
url.getFile() to remove a double-slash when present.
Fixes gh-5287
Closes gh-5289
Previously, FindMainClassTask would look for a property named main
on any class named run. This was based on the assumption that the
run task would be a JavaExec task (typically provided by the
application plugin). If the run task was not a JavaExec task (more
accurately, if it did not have a main property) this would result in
a build failure due to trying to read a non-existent property.
This commit updates FindMainClassTask to only use the main property
of the run task if the task is a JavaExec task. This guarantees that
the property will exist on the task, and unlike using any property
named main on a task named run, also guarantee that its value will
refer to a Java class with a main method.
Closes gh-5501
Previously, Animal Sniffer checking of spring-boot-loader-tools
was disabled as it failed with an NPE. This has been fixed in
Animal Sniffer 1.15.
This commit upgrades Animal Sniffer to 1.15 and adds the necessary
annotations to suppress failures for safe usage of sun.* and Java 7
APIs.
Note that UsesUnsafeJava has been copied from spring-boot and made
package-private. This retains the clearer intent of the custom
annotation (versus @IgnoreJRERequirement) while avoiding the change
in the build order that would be necessary for
spring-boot-loader-tools to use the annotation from spring-boot.
Closes gh-5284
Commit 5a1ee6eb added support for disabling use of start-stop-daemon
via a placeholder in the default launch script. Unfortunately, that
placeholder was subsequently broken in 81a47639.
This commit reinstates the placeholder and adds tests to verify that all
of the placeholders in the launch script can be replaced and that they
have the required default values. Furthermore, it also allows the use of
start-stop-daemon to be configured via USE_START_STOP_DAEMON in an
app’s .conf file. This allows the configuration to be changed after the
app has been built.
Closes gh-4985
Previously, if an application’s main method threw an exception,
MainMethodRunner would catch the exception and call System.exit(1).
This meant that the JVM would exit, irrespective of whether or not
any non-daemon threads were running. In contrast, when an application’s
main method was invoked directly (in an IDE, for example) the JVM
would not exit if one or more non-daemon threads were running. This
is standard JVM behaviour that we should be consistent with in the
launcher.
This commit updates MainMethodRunner to wrap any exception thrown by an
application’s main method in a RuntimeException and rethrow it. This
alllows the JVM to handle the exception and use its normal rules for
deciding whether or not it should exit.
Closes gh-4984
Generalize the `skip` property to start and stop goals so that one
can control if the Spring Boot app is starting via a configuration
property.
Note that this only controls the Spring Boot Maven plugin and the
failsafe maven plugin should be updated accordingly.
Closes gh-4922
PropertiesLauncher creates a ClassLoader that is used by the Launcher
to load an application’s classes. During the creation of this
ClassLoader URLs from its ClassLoader. This resulted resulting in Java
agents that are added to the system class loader via the -javaagent
launch option being available on both the system class loader and the
created class loader. Java agents are intended to always be loaded by
the system class loader. Making them available on another class loader
breaks this model.
This is the same problem that was in ExecutableArchiveLauncher and
that was fixed in ee08667e (see gh-863).
This commit updates PropertiesLauncher so that it skips the URLs of
any Java agents (found by examining the JVM’s input arguments) when
copying URLs over to the new ClassLoader, thereby ensuring that Java
agents are only ever loaded by the system class loader.
Closes gh-4911
Previously, the default launch script would send SIGTERM once and then
wait for up to 60 seconds for the app to have stopped. If the service
was stopped immediately after being started the first SIGTERM would
occasionally be ignored (presumably because the JVM was not yet in a
state to handle it) causing the service stop request to fail.
This commit updates the launch script to resend SIGTERM to the process
if it's still running 30 seconds after the first SIGTERM was sent.
Closes gh-4941
$arguments needs to be split on spaces so it can’t just be wrapped
in quotes. This commit updates arguments to be an array that is then
expanded ("{arguments[@]}"). The use of @ and double quotes means that
it is expanded into all elements individually quoted.
See gh-4866
This commit completes the changes to consistently used static final
fields for Log instances that were started in ec2f33f9. Specifically it:
- Removes this. when accessing logger fields that are now static
- Renames some fields from log to logger
- Makes some logger fields static
See gh-4784
81a4763 introduced a regression when multiple RUN_ARGS or JAVA_OPTS were
configured. Rather than the JVM being launched with multiple arguments
all of the RUN_ARGS or JAVA_OPTS were passed as a single argument. This
caused unexpected behaviour and typically caused the application to fail
to start.
This commit updates the quoting of the arguments the are supplied when
launching the app using start-stop-daemon so that space-separated
entries in RUN_ARGS and JAVA_OPTS remain separate.
Closes gh-4866
Previously, the launch script used which to determine the availability
of start-stop-daemon. which isn’t available by default on all OSs.
For example, it’s not available by default on CentOS 5.
This commit updates the launch script to use type when determining if
start-stop-daemon is available. This improves the portability of the
script and makes the use of type consistent throughout the script.
Closes gh-4925
Previously, the launch script would wait for the pid file to exist
before continuing. This didn’t work 100% of the time as it left a
window where the file had been created but the PID had not been written
to it that could result in an incorrect report of the app failing to
start.
This commit updates the script to wait for the file to have a size
greater than zero before continuing. This ensures that the pid has
been written to the file before the pid is read from the file and used
to check that the process is running.
Closes gh-4923
Update exit code support to allow the ExitCodeGenerator interface to
be placed on an Exception. Any uncaught exception implementing the
interface and returning a non `0` status will now trigger a System.exit
with the code.
