[antlr-interest] Stangeness in example java grammar

You are exactly right.  Having the finallyHandler rule is the right way to
do it.

Hi
 
Example java grammar had (an unintentional?) strangness:
 
Can anybody please say if it was intentional and what were the reasons?
 
The 'try' rule
<RULE>
tryBlock
 : "try"^ compoundStatement
  (handler)*
  ( "finally"^ compoundStatement )?
 ;
</RULE>
 
When finally is present, then finally is set as a root node and try is it's
child.
 
Perhaps more logical would be?
<RULE>
tryBlock
 : "try"^ compoundStatement
  (handler)*
  ( finallyHandler )?
 ;
 
finallyHandler
 : "finally"^ compoundStatement
 ;
</RULE>
 
br,
Sander
