[antlr-interest] Stangeness in example java grammar

[Sander Mägi]

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
