The format is rather unusual.
The time is 16 bits: 5 bits for the hour, 6 bits for the minutes, and 5
bits for the seconds. 5 bits only allows 32 values (0-31) so the number
must be doubled, meaning that the time is only accurate to the nearest
two seconds. Also, the JDK rounds this down by subtracting one. The
doubling and rounding is performed by shifting one place to the left
and masking off the right-most bit respectively.
The date is 16 bits: 7 bits for the year, 4 bits for the month, and 5
bits for the day. The year is from 1980, i.e. the earliest date that
can be represented is 1980-01-01.

Running the invoker plugin with multiple threads against an empty
Maven cache results in strange build failures where Maven claims that
it cannot find a jar or pom file for an artifact that it should be
able to find. It would appear that Maven is unable to cope with
concurrent writes to its cache.
This commit removes the usage of multiple threads that was introduced
in 4e907f1.
Fixes gh-2389
If user runs an executable archive then it and its lib directory will be
on the classpath. Entries from loader.path take precedence in a way that
should make sense to users (earlier wins like in CLASSPATH env var).
Also added new integration tests to verify the behaviour (big improvement
on the old ones, which probably aought to be beefed up to the same
standard).
Fixes gh-2314
Previously, WarLauncher included its root on the classpath. It also used
a filtered version of its root archive to hide both the WEB-INF and
META-INF directories. This meant that files in WEB-INF and META-INF
could be found by the classloader (as they were on the classpath) but
could not be read as the filtered archive was hiding them.
This commit updates WarLauncher to remove the root of the war file from
the classpath. It also removes the filtering of the archive, thereby
allowing files in META-INF and WEB-INF to be accessed via the
ServletContext.

* Windows: allow absolute file paths without file:/// prefix
* All: only add nested archives (not directories), so loader.path=lib/*
behaves the same as -classpath=lib/* (except for adding zip files)
Fixes gh-1352
The ExplodedArchive would erroneously always attempt to filter
its contents (and thereby shield them from a classloader that wrapped
it) even if they haven't been explicitly provided.
See gh-1352
Use Java 7 `registerAsParallelCapable` and `getClassLoadingLock` methods
when possible. This should improve performance when running on JDK 7+
whilst still remaining JDK 6 compatible.
