"antlr" is script doing: CLASSPATH=/usr/share/java/antlr-2.7.5.jar /usr/bin/gij antlr.Tool

And it works only just after entering the chroot. After "su -" (to root or
anything else) it crashes. 

I would like to keep using gcc-java for antlr, so it is available for all of our architectures,
but it just don't work (with the single exception provided above) :-(

Greets,
