    [ https://issues.jboss.org/browse/DROOLS-632?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13015591#comment-13015591 ] 

Roman Stumm commented on DROOLS-632:
------------------------------------

We had the same problem after upgrading from jetty 9.1.0.v20131115 to jetty 9.2.3.v20140905.
The reason is that the jetty WebAppClassLoader hides classes (e.g. the eclipse compiler and all classes in package "org.eclipse.jdt."). This can be changed, see org.eclipse.jetty.webapp.WebAppContext.getDefaultServerClasses() and setServerClasses().
