[antlr-interest] Out of memory error

[Mark Bednarczyk]

I keep getting the out of heap memory error under certain conditions, and
I've been trying to figure out how to specify vmargs to the ANTLR3 task so
that I can increase the defaul 64mb to something like 512mb. Anyone know how
to do that. ANTLR3 task doesn't provide any VM options. I did verify that
ANT spawns a new java VM to run the subtask for org.antlr.Tool with process
explorer.

Here is the rule that triggers this error. If I comment out the second
alternative, I don't run out of memory:

tableBody
	:	('{' tableConstant)
		=> ('{' tableConstants blockStatement* '}')
		-> ^(SLIST tableConstants+)
		
	|	'{' blockStatement* '}'
	;
