I've just updated my both normal fpc and jvmbackend port to revision 19992. However, the resulting compiler from normal fpc cannot be used to compile the jvmbackend port. It fails when compiling system unit, with these messages:

The same as always: the latest release. As of January 1st, 2012, that means 2.6.0

OK, I finally have a reason to use stable release...
