[rules-users] ClassCastException when debugging as a drools unit test with a ruleflow

[H.C.]

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.
