"Fiji won't quit" after uploading to sftp site on Windows #61

Open imagejan opened 7 years ago

imagejan commented 7 years ago

When uploading updates to an update site hosted via sftp (on Windows), Fiji continues running but cannot be closed. The upload is successful and Fiji remains responsive, but Fiji can only be quit by killing the process in Windows task manager.

I reproducibly observe this since a while, but only now managed to report it, since the workaround of just stopping the process (and deleting the ImageJ-xxx-stub file from the temp directory) worked fine.

I can reproduce this on Ubuntu 20.04 as well.

@tibuch Thanks. To find out why, you can run Fiji from the command line, then press Ctrl+\ after it hangs to get a thread dump. Looking through those traces may reveal what's holding on to the JVM. Or you can simply paste the thread dump here, and I'll take a look.
