#15 Freeze on save

[Pierre-Yves B.]

Hello,

When I edit a file opened in the Hex Editor and then press save, Eclipse freezes indefinitely. Force quitting Eclipse doesn't even solve the problem, I have to shutdown my macOS entirely and manually delete the workspace lock on restart.

Here's the relevant stacktrace from Eclipse's UI responsivness monitor:
