             Summary: Avoid JITting constraint if the used PermGen size is above a given threshold
                 Key: JBRULES-3569
                 URL: https://issues.jboss.org/browse/JBRULES-3569
             Project: Drools
          Issue Type: Enhancement
      Security Level: Public (Everyone can see)
            Reporter: Mario Fusco
            Assignee: Mario Fusco


JITting all the constraints used in a large rule base can cause an OutOfMemory error in the PermGen space. Before to JIT a constraint it is necessary to check if the PermGen space currently in use is above a (optionally configurable) threshold and in this case avoid the JITting and let the constraint to be evaluated in interpreted mode.
