It works with ANTLR 2.7.7 on my machine at work:

cthalinger@cthalinger:~/projects/classpath/classpath/build/tools$ make
JAVACFLAGS="-nowarn"
/bin/mkdir -p classes asm
/bin/mkdir -p generated/gnu/classpath/tools/gjdoc/expr
runantlr -o generated/gnu/classpath/tools/gjdoc/expr \
          ../../tools/gnu/classpath/tools/gjdoc/expr/java-expression.g
Running java antlr.Tool $* with /usr/share/java/antlr.jar appended to the CLASSPATH
variable

Maybe this is the same problem as in #129. twisti, do you remember which compiler you
used to build CACAO? Or if you built with optimization at all?

Sorry, I have no idea.
