Re: How to handle "java.lang.IllegalStateException: The EventAdmin is
stopped" during shutdown
Hi Carsten,
It has been some time since I last tried newer versions of the
EventAdmin, but I am now testing the 1.2.12 version.
While I don't see the IllegalState problem any more, I do see a NPE
when shutting down the framework while sending events.
The stacktrace is:
Exception in thread "Event Test Generator" java.lang.NullPointerException
at org.apache.felix.eventadmin.impl.handler.BlacklistingHandlerTasks.createHandlerTasks(BlacklistingHandlerTasks.java:116)
at org.apache.felix.eventadmin.impl.EventAdminImpl.sendEvent(EventAdminImpl.java:108)
at org.apache.felix.eventadmin.impl.security.EventAdminSecurityDecorator.sendEvent(EventAdminSecurityDecorator.java:94)
at mc.product.fmcw.test.eventgenerator.FMCWGenerator$1.run(FMCWGenerator.java:55)
at java.lang.Thread.run(Thread.java:680)

Yes, I think I saw this one as well occasionally - can you please create
an issue for this one?
I'll take care of it then.
