Thanks. I think that means I need to patch ant ( I'm using ant with
build.compiler=gcj ).

That would be quite difficult. If you want to reproduce it - all the 
code is available ( but not easy to compile - you'll need 4-5
repositories from jakarta ).
The file with problems is:
http://cvs.apache.org/viewcvs/jakarta-tomcat-jasper/jasper2/src/share/org/apache/jasper/compiler/Generator.java
There are actually a lot of problems with this file - but I got around them by
refactoring the code and moving some inner classes around. It seems
gcj still has problems compiling inner classes declared inside a method.
