Re: [platform-swt-dev] Webstart process fails to terminate (Win32 SWT 30

[Jesse Hill <Jesse_Hill@xxxxxxxxxx>]

Which platform is this? win32 should
clean up automagically but I've seen problems on pocket pc where the window
procs must be terminated explicitly (by correctly disposing your widgets)
or they prevent the vm from shutting down cleanly.

SWT absolutely does not create any threads on your behalf.  When you
exit, resources are automatically reclaimed by the operating system.

Subject	[platform-swt-dev] Webstart process fails to terminate (Win32 SWT 3044)

I'm deploying a SWT application via webstart.  When the application
exits,
the webstart process (javaw.exe) was failing to terminate, such that when
I
deployed an updated version of the application and tried to launch it,
it
couldn't unpack the DLL jarfile, because the old copy of the .dll's were
still in use.

I used Sleak to find resource disposal problems and found I wasn't disposing
my images, fonts, and colors, and now I think the problem has been
corrected.

I also dropped back to Sun JRE 1.4.2_04, whereas I had been testing on
Sun
1.5.0.

When I run the application from the command line I don't have this problem,
the Java runtime exits normally.

So here's the question: is there a daemon thread or something that continues
running in SWT until I free up ALL of my resources?  Why would this
application exit when run standalone but not under Webstart?

Thanks,

- Jason
