#4101 jEdit hangs if file can't be saved
I was fixing a few things in the Sessions plugin and was testing it out. Previously, I had opened an XML file from a tablet via USB in jEdit, then later unmounted the tablet and forgot the file was open in jEdit. I changed sessions in the Sessions plugin, and was asked if I wanted to save the changes to the XML file. I said yes (not noticing it wasn't a local file), and jEdit hung. I had to kill the process to get it back.
The last message in the activity.log was:
[jEdit Worker #0] [error] BufferSaveRequest: Unable to save buffer java.io.FileNotFoundException: /home/danson/mnt/tablet/Internal shared storage/bluetooth/Barb s Zoom.mss.xml (No such file or directory)
A thread dump shows this:

There are some synchronized blocks in TaskManager that are probably causing the problem, but I'm not familiar with this part of the code.
I've never thought to submit a bug for this, and it's happened pretty much since I started using jEdit, but this happens for remote server work as well when using the FTP plugin.
Would be a pretty big fix in my books because I have to change the way I work to ensure I don't get caught by this (which I've almost trained myself to do over the years). Thanks for logging this.
