What is the current status of GCJ at the moment (mid 2009)? The latest news are from 2007, so I'm wondering if there is any form of progress? I remember that there was a while ago a compiled version of lucene available which used gcj to compile it from the java sources. Is there any other high profile project which uses gcj at the momen...
