Hi all!

I invoked workbench.close() in WorkbenchAdvisor.postStartup() and
exception is occured:

please provide the code that causes the exception.

Hi Rüdiger,

I changed startup behavior now and don't close workbench anymore.

I closed workbench in postStartup() method, because comment for
WorkbenchAdvisor.postStartup allows it: "It is okay to call
<code>IWorkbench.close()</code> from this method." I used this ability
to check license, show error and close application in RCP based application.
