> 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 :)
