    Description

      Any code that does `new Thread()` on GAE throws an exception, because you can't create new threads yourself.
      Other future cloud platforms might have a similar restriction. It should be possible to plug in a custom way of creating threads.

      Proposal A) Add a kieBase configuration property to change the ThreadFactory

      drools.threadFactory = com.user.project.GoogleAppEngineThreadFactory

      Proposal B) Add a kieBase configuration property to change the ExecutorServiceFactory

      drools.executorServiceFactory = com.user.project.ExecutorServiceFactory

          • Blocker - To be worked above all other priorities. This term is chosen when the severity of the issue is very high, has no workaround, or the effort for the change is comparatively low. Issues that may be very publicly visible and could generate significant media attention may also drive a higher priority.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
