I mean run antlr on it.. like
java org.antlr.Tool <Grammar>

Here is the problematic part:
===============
curly_block 
 : 
 {true}? LCURL exprs? RCURL -> TEXT[$LCURL] exprs? TEXT[$RCURL] | 
 LCURL exprs? RCURL -> exprs? 
 ; 
===============

remove it and uncomment the following

=================
 /* 
 curly_block 
 : 
 LCURL exprs? RCURL -> TEXT[$LCURL] exprs? TEXT[$RCURL] 
 ;*/ 
================

So it compiles.

I'd like to add this directly to JIRA, but couldn't find a way to Log in.
