Description

Bugtraq ID 6380355
The browser gets a NullPointerException when used to destroy a service that implements Administrable and whose administrative
interfaces include DestroyAdmin but not JoinAdmin. The browser does succeed in destroying the service, but produces an error
pop-up window with the title "java.lang.NullPointerException" and no text, and produces a stack trace as logging output.

Here's sample logging output for the problem:
