ARE hangs (related to Open File dialog?!)

[klues]

We observed a similar error two times:

• ARE was started
• Tried to open a file using the file dialog in the control bar ("Choose a new model")
• after selecting a model, the open dialog closes and ARE hangs, no GUI operations are possible anymore and no error log messages
• Once we pressed Ctrl + C in the console, trying to kill the hanging ARE, and this caused ARE to open the model selected before and an empty file open dialog suddenly re-opened
• afterwards ARE worked without problems, also after restarts

We made two thread dumps:

• hanging_after_open_file_dialog.txt
• not_hanging_file_dialog_is_open.txt

On comparing these thread dums 2 things are interesting:

• in the hanging application a thread Swing-Shell exists and is in state WAITING, which certainly corresponds to an open file-dialog, although it was not visible in the hanging ARE
• In the hanging ARE the thread AWT-EventQueue is in state RUNNABLE, while in the normal ARE it is WAITING while the file dialog is open.

solved the issue: the problem was that the windows console (cmd) stops any running thread if selecting something ("Quick edit mode"). See: https://stackoverflow.com/questions/33883530/why-is-my-command-prompt-freezing-on-windows-10

Therefore this is no bug in AsTeRICS.
