Still in freeze mode after 2 hours so getting the stacktrace was fortunately easy...

I guess the push dialog blocks the credential dialog

> I guess the push dialog blocks the credential dialog

I guess you should minimize all windows and check if you can find the login dialog. Sometimes you only need to re-order the opened windows to see it.

Next time just attach the full jstack file to the bug as file, not only UI thread stack.

jstack pid is not sufficient?

I guess that you are looking for "jstack -l pid". Will try to reproduce and add this info.

No,sorry, for whatever reason my browser cut of the rest of the stack below main, may be just connection was killed, no idea. Will check the stack later.

I think Lars's comment 4 is on the right track. A modal dialog was open, and the LoginShell is a second modal dialog, but parented off the main window. That's asking for trouble in any case, and possibly the login dialog appeared below the "Configure Push" dialog.

I think EGitCredentialsProvider needs to use PlatformUI.getWorkbench().getModalDialogShellProvider().getShell() instead of PlatformUI.getWorkbench().getActiveWorkbenchWindow().getShell() to get the parent shell of the login dialog. Then the login dialog would be parented off the progress dialog.

Created attachment 281197 [details]
Not blocking anymore

Patch works fine, the other dialog is not blocking anymore for me.

Thanks, Thomas.
