I am already aware of this problem. Only java packages which are not build via
ant are affected - thats the minority.

No, its not intentional and no package needs to specify anything unless I have
filed a bug report against them.

The problem is that kaffe now uses ecj-bootstrap as its compiler. Using kaffe
via ant directly uses a programming interface and compiles against kaffes
runtime classes. Compiling with the javac command is (currently) a link to
/usr/bin/ecj.

The problem is that ecj-bootstrap is the source of the failure. It somehow
needs some setup from java-gcj-compat to fullfill its job. You can easily
verify this by installing java-gcj-compat and compiling a simple
HelloWorld.java with /usr/bin/ecj-bootstrap which will work. Removing
java-gcj-compat and it will fail. However, where the problem is is still
to be investigated.

The other (upcoming) fix will be that kaffe uses its own wrapper script
against ecj-bootstrap to compile against its runtime classes. This will be
added in the next uploads and fixes the problems regardless of ecj-bootstrap.

I will therefore clone this bug report and reassign to ecj-bootstrap.
I will let it open against kaffe until the new wrapper script is added.
