[antlr-interest] Newbie re: memory management on parse fail (C++) and Java

[Matthew Ford]

Has anyone check for memory leaks in the Java version?

I know Java has automatic garbage collection but if the references to
objects are not handled correctly you end up with old unused objects trapped
in memory because of a  reference that has not been cleaned up.
