We experience problems to gracefully shutdown the JVM because Shoal does not terminate all non-deamon threads upon shutdown.

We initiate Shoal shutdown via the following API call but this does not terminate the GMSContext "viewWindowThread" and "messageWindowThread" and the Router "signalHandlerThread" (non-daemon) threads.


To work around this problem we had to implement the following hack:

DirectFieldAccessor gmsContextDirectFieldAccessor = new DirectFieldAccessor(gmsContext);
gmsContextDirectFieldAccessor.setPropertyValue("shuttingDown", true);

Router router = gmsContext.getRouter();
DirectFieldAccessor routerDirectFieldAccessor = new DirectFieldAccessor(router);

Kindly fix this shutdown issue. Please let me know should you require a proper source code patch for this.

this shoal gms issue would prevent glassfish v2 and v3.1 and higher application server from exiting.
It has been fixed in all versions of shoal gms.
