Description Michael Spector CLA 2011-08-10 06:38:21 EDT 
One of our users has encountered this exception while upgrading his Eclipse RCP application. This looks like a bug:

!ENTRY org.eclipse.core.jobs 4 2 2011-08-08 17:07:10.767
!MESSAGE An internal error occurred during: "Installing updates...".
!STACK 0
java.lang.IllegalStateException: Profile profile is not current.
	at org.eclipse.equinox.internal.p2.engine.SimpleProfileRegistry.lockProfile(SimpleProfileRegistry.java:691)
	at org.eclipse.equinox.internal.provisional.p2.engine.Engine.perform(Engine.java:44)
	at com.stepwell.rcp.update.P2Util$1.run(P2Util.java:211)
	at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)


The class P2Util is attached.

This happens when you are trying to start an engine operation on a profile that is not the most recent one. 
This is likely a bug in your code.

I'll appreciate if you elaborate a little bit on this. I'm not a p2 equinox core developer, so what you said looks to me like a magic spell. I'm using the same PDE build process for at least a year, none of build parameters has been changed since then. I also use "standard" P2Util for running seamless upgrade, which I've found under Eclipse repository. Nevertheless, one of our users has received such a message. Where should I look for bugs?

Thanks.

I think you cannot just close such a bug by saying "works for me". You can't be sure that your framework works in 100% of cases, and this is why we (consumers) of the framework are useful in finding these non-working cases.
Comment 5 DJ Houghton CLA 2011-08-17 15:51:43 EDT 
Pascal, is this a case where the new simplified Operations API that was released for Indigo might help?
Comment 6 DJ Houghton CLA 2011-08-17 15:55:21 EDT 
And by "help" I mean it would simplify the user's code for discovering and applying updates.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
