[Dev] Exception prevents running non-jython test scripts on Apple's Java 6.0 JVM

[Olivier Dony]

Dear all,

We have been trying to run Groovy test scripts using the latest  
version of TestMaker (updated from CVS just now) on Mac Os X.

It is apparently mandatory to use a java 6 JVM for the jetty-based  
testnodes, as a lot of JAR dependencies are compiled for 6.0 (e.g.  
browserjs-engine.jar, groovy-engine.jar, etc.).
However when the TestNode is started using the Apple JVM 6.0 (the one  
and only developer preview release), it fails to execute our groovy  
script due to the ClassCastException below.

Note that the script runs fine within TestMaker when executed locally  
through the Agent->'Run Script locally...' menu.
It also works when we use a jython script, presumably because the  
TestRunner does something different for jython than for other  
scripting languages, in methodFromCallScript().

The issue could be a conflict due to duplicate JSR-223 APIs in the  
classpath, similarly to the issue described on this page : http:// 
weblogs.java.net/blog/robc/archive/2007/03/using_phobos_wi.html#c27286
(however simply removing the script-api.jar from the webapp libs  
doesn't work)

We are still trying to work around this issue, so any help/thoughts  
are welcome!
