Submitted PR #1997 proposes a cache lookup for Method accessor for FEEL (EvalHelper#getGenericAccessor) but missing cache eviction make the optimization incompatible with KieContainer upgrade. This JIRA will provide report on optimization and cache eviction mechanism.

Before, baseline of reference:

After, with cache eviction as proposed by PR #1997

We can notice the EvalHelper method is no longer a "hot spot" and the 10K evaluations of the model takes less than the creation of the DMNRuntime hence is no longer the top expensive operation in the test.
