Comments
Wildcard processing is done differently with a custom implementation as JDK7 see: http://hg.openjdk.java.net/jdk7u/jdk7u-dev/jdk/rev/7af05e99ff0e You might want to set env variable _JAVA_LAUNCHER_DEBUG=true and execute the commands that will give you an insight of what is going on.

Probably not a javac bug, but more like a launcher bug. Both -J processing and *.java expansion happen before javac is started. Reassigned to tools/launcher.
