[antlr-interest] java.lang.OutOfMemoryError: Java heap space

[Diane Nkonyereza]

Hi,

When I run my grammar in ANTLRWorks I get the error below. It only happens when I run it for the 2nd or 3rd time. The 1st time there is no problem. For that reason I think it's nothing to do with my grammar. What's the cause of the error and how should I resolve it.

Thanks in advance,
D.
