---------------------------------------

             Summary: lambda expressions cannot be parsed by ecj/janino
                 Key: DROOLS-1009
                 URL: https://issues.jboss.org/browse/DROOLS-1009
             Project: Drools
          Issue Type: Feature Request
    Affects Versions: 6.3.0.Final
            Reporter: Malte Brunnlieb
            Assignee: Mark Proctor


Using Java8 lambda expression in the decision template like 

bean1.call(() -> $param); 

you will run into compiler issues with ejc as well as the currently supported version of JANINO (2.5.16). I tried to manually upgrade the JANINO compiler version, but got stuck in compatibility issues as the Scanner seems to have been changed regarding exception handling. 

Can you suggest to fix the incompatibility with JANINO > 2.5.16 such that lambda expressions can be parsed by the newest parsers? Would be nice :)
