Hi,

please optimize your signal/noise ratio:

* try to reduce your use case to a minimal test case which still exhibits
the erroneous behaviour
* a self contained unit test would be perfect
* try compiling the files from your use case using a plain KnowledgeBuilder.
As the Ant task is merely a wrapper around it, try to reproduce the
erroneous behaviour with the simplest setup possible.
* put the rule source code into your test as string literals.
* reduce the rule source code as much as possible while still reproducing
the error
* then, identify the smallest rule source code delta which makes the error
go away.

If you finally manage to reproduce the error using this minimal setup, make
sure to include complete information. In particular, don't XXX out parts of
the error message.

I'm quite sure if you follow at least some of these hints, you will probably
get more feedback from this list.

Best regards,

Ansgar
