[antlr-interest] error with modulo operator in tree grammar action

[Michael Bedward]

Hello all,

I search the list for this but only found a related bug report - no solution.

I have a rule and associated action (java) in my tree grammar...

expr: ^(MOD a=expr b=expr) {$value = a % b;}

This provokes get an invalid string template error.  I imagine there
must be some simple option or similar that I'm missing (?)
