Andy Wilkinson cdcc3d2f28 Ensure getResources("") includes nested root URLs ... Previously, if Boot's JarURLConnection pointed to the root of a nested entry, e.g. /BOOT-INF/classes, a call to getInputStream() would throw an IOException. This behavior is reasonable for a URL that points to the root of a normal jar as the jar itself is on the class path anyway. However, for a nested jar it meant that a call to ClassLoader.getResources("") would not include URLs for any nested jars and directories (/BOOT-INF/classes and jars in /BOOT-INF/lib). This is due to some logic in URLClassPath.Loader.findResource that verifies a URL by opening a connection and calling getInputStream(). The result of missing URLs for the root of nested jars and directories is that classpath scanning that scans from the root (not a good idea for performance reasons, but something that we should support) would not find entries in /BOOT-INF/classes or in jars in /BOOT-INF/lib. This commit updates our JarURLConnection so that it no longer throws an IOException when asked for an InputStream for the root of a nested entry (directory or jar). Fixes gh-7003		8 years ago
