This is strange because our CI server (hudson) is green on all tests, as well as my local build here...
   The error:

org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java'

   is usually associated with a wrong JDT version being used in the classpath... although, if you are using maven to build, that should never happen...
   May I suggest you remove your local maven repo for the eclipse dependency $HOME/.m2/repository/org/eclipse/jdt/core and try again?
