Hello,

I am using Trace Compass 3.3.0 version as part of my project.
I am getting below exception while exiting the application, can you please help to avoid this.I am starting my application from Command prompt, so exception is visible to users.

Hi Raghava,

That is very strange. The factory is normally registered in tmf.ui.Activator.start() and deregistered in tmf.ui.Activator.stop().

The message that you see is printed by the TmfSignalManager when it gets disposed in tmf.core.Activator.stop().

At that point we normally expect that the tmf.ui.Activator.stop() has already been called. The tmf.ui plugin depends on tmf.core, so tmf.core should be started first, and stopped last if the platform stops bundles in reverse order that they were created.

Looking at the code, a few (unexpected) possibilities that could lead to this leak would be:

1. tmf.ui is not stopped at all
2. tmf.core is stopped before tmf.ui
3. tmf.ui is started twice without being stopped in between, then stopped
4. tmf.ui and tmf.core are stopped concurrently in different threads
5. tmf.ui.Activator.stop() does not complete due to an Exception being thrown

But in most of these cases, there would be more leaks reported due to other unregistered listeners in tmf.ui.Activator. Are you seeing just this one leak or are there more in the console?

Can you think of anything in your application that would influence the activation of tmf.core and tmf.ui plugins?

Best regards,
Patrick

Thanks Patrick for quick response.

We could see below exception also. We are importing the files into trace project and opening the views. we are not customizing any of the code.

Resource leak: org.eclipse.tracecompass.internal.tmf.ui.views.TmfAlignmentSynchronizer@2e3ec0e9 was not deregistered.
org.eclipse.tracecompass.tmf.core.signal.TmfSignalManager.register(TmfSignalManager.java:86)
