Since I updated to 0.6.21 because of the long expected fix of bug 1903265, this seems to be fixed but in rare cases the editor freezes after a new function was created and a few characters has been typed. It's necessary to close Eclipse and restart it after it. The file contained the unfinished method gives:

Here a log when EPIC editor crashes during typing ...
Same problem, I'm cosing sth. and when typing an 's' the editor stops further working for this file.
I'm usually going to use gvim to fix the code (because EPIC won't open the file until the code has been fixed there).
