Hi,
I'm using VisualVM to monitor and profile a RAP application and I've noticed that some instances from the classes of the application are not garbage collected once the rap application and the client's browser have been closed.

For example the classes that extend from ActionBarAdvisor, WorkbenchAdvisor, WorkbenchWindowAdvisor are some of these instances.

Does these instances suppose to be alive once the application has been closed?
If not, is there a way to release them so they can be garbage collected?

Hi,

what is the session timeout you are using? I would expect some things to
stick around until the session times out.

Elias.

Hi,
I'm setting to a 1000 the field session timeout of the runtime settings in the launch configuration of the application. I don't really know if the value are seconds or milliseconds, but I'm guessing that are milliseconds.

No, it's seconds, as the label says: "Session timeout [s]". To be able to
test session cleanup, you'll have to set it to a lower value. I'd
recommend ~30-60s, to be able to simulate some user interaction. Then you
wait for session timeout, create a heap dump, analyze it...

Regards, Ralf
