[jboss-jira] [JBoss JIRA] (DROOLS-1009) lambda expressions cannot be parsed by ecj/janino

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: Mario Fusco Fix For: 6.4.0.Beta1 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 :)
