This is because some pending feature. I planned to implement headless
starting of application servers (first tried Glassfish). There was a
problem, that the server adapter fires some status change event, and
the debug plugins in eclipse are consumer for it. As event handler
they do some GUI action, that screwed up my headless eclipse with an
infinite loop. So I looked after how to remove extensions. You need to
connect to plugin repository, but for it you need to hack, because
mastertoken i do not know where to set. This is why it is like this.
