[rules-users] JUnit Test failure when Eclipse library present on classpath

[StormeHawke]

I'm not really sure what to make of this, but when the Drools Runtime library
is present on my project classpath, any of my junit tests that reference
Drools fail, but if I remove the runtime library from that same classpath,
everything runs as expected.  The output in the console:

Build groovy files option has not been set one way or the other: use
'options.put(CompilerOptions.OPTIONG_BuildGroovyFiles,
CompilerOptions.ENABLED);'
(I'm not using groovy files of any kind)

But then I also get a really long stack trace in the JUnit output pane
(truncated once it reaches my code):

To top it off, the same test runs fine on my boss's computer, but not on
mine.  Neither of us is sure why.  What am I missing?
