      • Create a simple rule file with an MVEL dialect set
      • Configure a breakpoint inside the rule file
      • Execute the rules inside an extra thread (not main thread) in Eclipse
      • The execution does not stop on the breakpoint
      • when the rules are executed in the main thread, the execution stops on breakpoint
      • when the dialect is JAVA, the execution stops on breakpoint when executed in the extra thread too

      The debugger does not stop on the breakpoint within a rule consequence when the dialect MVEL is used and the rule execution is done in an extra thread. The debugging is done in Eclipse using drools plugin installed. The project is a drools project and is debugged as drools application. See the attached application (drools-module.zip) to reproduce.

      When the rule execution is done in the main thread, the debugger stops on the breakpoint (workaround)
