Description Jaroslav Tulach 2012-12-01 07:00:12 UTC 
There seems to be a random problem in commit validation tests. I see it once from about four runs:


org.netbeans.core.windows.awt.ValidateLayerMenuTest.testContentCorrect

Failing for the past 1 build (Since #3943 )
Took 3.5 sec.

Comment 1 Martin Entlicher 2012-12-01 08:19:32 UTC 
I was not able to reproduce it yet, according to investigations so far it looks like org.netbeans.modules.php.dbgp.breakpoints.BreakpointActionProvider does not get created and thus the lookup contains null instead of it's instance, resulting in a NPE:

java.lang.NullPointerException
	at org.netbeans.api.debugger.ActionsManager.registerActionsProviders(ActionsManager.java:490)
	at org.netbeans.api.debugger.ActionsManager.initActionImpls(ActionsManager.java:517)
	at org.netbeans.api.debugger.ActionsManager.isEnabled(ActionsManager.java:275)
