Description

Assaf, does jruby -S spec spec/java_test_frameworks.rb goes green for you?

java_test_frameworks.rb was failing for me when running with JRuby, printing the following stacktrace for each spec example:

org.apache.tools.ant.BuildException: Errors while applying transformations: Fatal error during transformation
AggregateTransformer.java:266:in `org.apache.tools.ant.taskdefs.optional.junit.AggregateTransformer.transform'

I managed to get it working by adding the classpath jars to the systemClassLoader instead of using the jrubyClassLoader, I don't know if this is the best solution, anyway I've attached the patch that makes it work for me.
