[jboss-jira] [JBoss JIRA] (DROOLS-362) Make Drools work with Janino 2.6.1 and javax.tools API

[John Engelke (JIRA)]

     [ https://issues.jboss.org/browse/DROOLS-362?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

John Engelke updated DROOLS-362:
--------------------------------

    Description: 
Drools can be set to leverage the Janino "super-small, super-fast Java(TM) compiler." But it only works with version 2.5.16, not the latest version 2.6.1. 

Unfortunately, Janino does not support language features above 1.4/1.5 (partial 1.5). 

Version 2.6.1 includes an option to use the JDK built-in javax.tools.JavaCompiler: "JANINO can be configured to use javax.tools.JavaCompiler (available since JDK 1.6), i.e. JAVAC, which removes the Java 5-related limitations." [ See http://docs.codehaus.org/display/JANINO/Home#Home-what ] Unfortunately, this is only available when using the jars commons-compiler.jar and commons-compiler-jdk.jar, which are themselves only available in Janino 2.6.1. [ See http://docs.codehaus.org/display/JANINO/Advanced ] 

This is a nice little blocker for those of us who don't totally agree (or simply cannot agree) with the Eclipse license. Eclipse JDT is out. And, apparently, so is the double-diamond operator (until this is fixed)! 

Thanks.
