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) On 14 February 2011 15:21, Carsten Ziegeler wrote: > Hi, > > I just fixed another shutdown problem in the event admin, so maybe you > want to try latest version from svn trunk > > Regards > Carsten > > Am 17.01.11 17:35, schrieb Alexander Broekhuis: >> Hi Carsten, >> >> Will do, I also tested with older versions, and 1.0.0 works ok.

Hi Carsten, Will do, I also tested with older versions, and 1.0.0 works ok. So I will use that version for now.

Re: How to handle "java.lang.IllegalStateException: The EventAdmin is stopped" during shutdown
Hi Alexander; Are you using the dependencymanager from the trunk ? If so, then I assume that you are also using the dependencymanager compatibility bundle, because I see that you are using the old "org.apache.felix.dependencymanager" package ? In this case, you might have found a bug from the DM compatibility bundle. Please open a jira issue for DM, and attach to it your sample code, I will then investigate. (I think that your Sender.stop method is not properly invoked by the DM compat bundle).

Hi, which version of the event admin are you using? And can you post all exception stack traces you see?
