      Description

      Micro benchmarks on EJB local session beans have regressed by 30% in current build. This is because of implicit CDI; if I set cdi-enable-implicit=false, performance reverts to previous levels.

      I suspect this is a new weld integration to fix for https://java.net/jira/browse/GLASSFISH-20474 – and the memory leak is fixed, but we are left with the new performance regression.

      The WeldListnener is consuming about 30% of total CPU now, particularly in the WeldListener.requestDestroy() method.
