Hi,
I have a unit test written which tests my rules. In my setup, I am loading
my drl and rf files via a changeset into an agent and getting my knowledge
base. The test then sets globals and facts on my stateful session and
execute my ruleflow. I can execute this unit test in JUnit and debug. My drl
and rf files build ok and I can step through my java breakpoints.
However, when I execute the very same Junit test using debug as Drools Junit
Test, I get the following exception when the knowledge agent is building my
drl and rf files in my junit setup.
The only difference between the two scenarios is that I am using the debug
as Drools Unit Test in the exception scenario and plain debug as junit test
in the first. I make no configuration or code changes.

That is strange ... Only thing I can image is that you are using the
internal drools jars that are shipped as part of the eclipse plugin in the
Drools JUnit case and not in the normal JUnit case. Could you try updating
to the latest snapshot version of the Eclipse plugin (this will update your
internal Drools jars)?

9 p.m.
Kris,
Thanks but same error. I tried both the 5.1.0.M1 plug-in and the trunk
snapshot you gave me. Same error every time. I have also made sure my drools
runtime is 5.1.0.M1 jars.

I've just tried debugging a unit test with the latest snapshots and don't
have any issues. So if you can reproduce so I can take a look, please let me
know. Other than that, I can only recommend to take a fresh eclipse,
install the latest snapshot plugin and create a new runtime (based on the
jars included in the plugin). That really should work.
