Hi,

Can you try to run the tests without the livetribe-jsr223-2.0.6.jar on the classpath? This jar contains the javax.script classes, which are missing when running on Java 5 environment. I'm guessing that these classes are colliding with the ones on your JDK.

Hi Frederik Heremans,

Yes, it works! All tests PASSED now. Is that means the library is needed in JDK5 environment only, but not JDK6 and onward?

Thank you very much!

@Chee: thats indeed the case. The livetribe jar is an implementation of the javax.script classes which are part of JDK6, but not of JDK5.

Congrats with the green tests 🙂

Chee,

Apparently some classloaders are more forgiving than others when it comes to duplicate class entries
