Summary: PropertySheet never releases member "currentPart" - causes memory leak

Description Andre Bergmann CLA 2011-11-03 10:50:29 EDT
Build Identifier: org.eclipse.ui.views (3.5.1.M20110202-0800)

The component org.eclipse.ui.views.properties.PropertySheet always keeps a refrence to the last part in its member "currentPart". Thus, even if all editors are closed, a reference is still kept and the gc cannot clean up the edior element (which is quite big in my case). 

Eclipse Memory Analyzer (MAT) shows, that "currentPart" references the editor instance, even if the editor is closed. 

My suggestion would be, to reset the member "currentPart" in partClosed(...) method if the closed part.equals(currentPart). 

Reproducible: Always

Actually that's the R3_development commit.

'master' fix is: a4f48217d6c3eecbc2eb99b01f3637096c179f69

The fix was only in the Eclipse 3.x stream. Now it is in both the 3.x and 4.x stream.
