> I'm using Drools in a relatively vanilla fashion -- not doing anything fancy; no custom DSLs or whatnot. I have a JUnit test case that invokes a set of rules. When the test case is run individually, it passes just fine. However, when the test case is run within a larger test suite (i.e., with other test cases), the test fails. When running the test suite, I do see an exception being thrown by Drools:

> I have experienced this behavior sporadically with other test cases as well. FYI, there is no *shared* data being consumed between test cases. Also, we are using stateless knowledge sessions. Each individual test case will get its own fresh stateless knowledge session instance.
> Is there a way to disable JIT'ing within Drools? (as this seems to be a JIT-related issue). FYI, I experience this issue in the following Drools releases: 5.3.3.Final, 5.4.0.Final and 5.5.0.CR1.
