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.
