Allow loader.path to refer to nested jars
Previously, each entry in loader.path could only refer to a standard jar file. Refering to such a jar would add all of the classes in the root of the jar to the class path. This commit adds support for referencing a directory within a jar file that contains one or more nested jars. For example: $ java -jar -Dloader.path='jar:file:./lib.jar/!BOOT-INF/lib' my.jar This will add all of the classes in all of that jars in the BOOT-INF/lib directory of lib.jar to the class path.
