A couple of points...
	- Unless you changed something, you should be noticing that
	 the Java code in libgcj is being built _without_
	 optimization. This could be having a big impact on your
	 application.
	- There's no clean way to pass flags to the java compiler from
	 outside the make system right now. There's a PR in the bug
	 database for this (#41).
Unless you are inspired to address pr41, all I can suggest is to edit
the Makefiles.
