[rules-users] running Test scenarios in Guvnor 5.2.0.CR1 causes a memory leak

[Michael Anstis]

You are correct, the decision table model changed between 5.1 and
5.2.0.Final.

You can load 5.1 tables into 5.2.0.Final but the model changed between
pre-release 5.2.0.CR1 and 5.2.0.Final to support CEP functions.

Guvnor uses Drools Expert to run tests and therefore problems in Expert will
affect Guvnor too.
