Re: [equinox-dev] equinox standalone problem

[Thomas Watson <tjwatson@xxxxxxxxxx>]

Are you certain you are using the Thread.setDaemon(false) method? If you are not then the threads will inherit their daemon status from the invoking thread. If this happens to be one of the daemon framework threads then your bundle threads will be daemon also.

One quick way to find out is to run with a console and run the "threads" command. It will tell you the daemon status of your bundle threads.

Well, that works but I don't really understand it. As I mentioned in
my previous mail, I actually have bundles installed that are creating
their own (non-daemon) threads so that should keep the jvm alive, no?

Thanks a lot for this workaround!
