(In reply to comment #0) > Build Identifier: M20100211-1343 Does this happen on 3.6? > 1. Close Eclipse/RCP and restart it. The stack trace indicates that the workbench window is being closed. Is restarting actually relevant?

Paul, Is WorkbenchWindowAdvisor.preWindowShellClose() calling WorkbenchWindow.close() a valid call?
No, you cannot call WorkbenchWindow.close() from within the preWindowShellClose(). WorkbenchWindow.close() must close the window before it returns, and preWindowShellClose() must return true or false to a WorkbenchWindow that's still in the transition state (since false can prevent its closing). PW
Thanks for the info guys. You can close this bug then as user error. We will fix our RCP code.
