coding?

happens too often

this happens quite often simply when coding. All highlightings disappear and i need to reopen the file

The easiest way to reproduce this is to try clicking on the "bug" link in the Exception Reporter tab. It's 100% reproducible :)

Sorry. Please ignore my last comment. I was confusing this with another exception.

Seems this occurs when you STOP typing

Dusan must be getting 10,000 emails a day from this issue by now :)

Do we need to improve logging for this issue, or do you understand what's triggering this?

This happens so frequently as to make the IDE unusable.

Typically after this happens 20-30 times, I wind up with the AWT thread frozen - not a deadlock per-se, since only one lock is involved, but these are the threads which share the NbEditorDocument - not sure if this is related or not:

err. log.

I am really looking forward to this being fixed, as
A) like Tim writes it is pretty disruptive to the experience, and
B) I am no fan of having the content of my java files logged in the IDE log. I use netbeans for my work, and as long as the class files are logged in messages.log i dont dare send in slowness reports or any other exception reports from the exception reporter directly, as i will not have my work classes shared with the world!

The attached stacktrace + debug is from daily build 201311050001.
