Is anything happening here?
It's been a month and this bug is really annoying.

It basically renders the whole IDE useless if a Java source file has errors but there is no quick way to identify where the error is.

Please try upgrading to 8.0 fcs, there were addressed such issues in the final release

I have. Problem still occurs though I cannot precisely tell you how to reproduce it.
Seems to happen when editing a lot of files in a big project.
If it happens again, I will try and upload the log here.

Isn't background indexing in progress whenever you notice the file errors are not marked in editor? FYI, the task that draw error marks in editor waits for background scan to be finished.

I'm not sure if some indexing is running. At least I didn't see any progress bar or other indicator that there is a Netbeans process running.

Anyway, the status I described did not change for minutes. Actually, I had to restart Netbeans to get Java editor working again.

So either the background scan is way to slow or it was not the problem.

Same situation here. Eventually after the yesterday's update.

Same problem here. Very annoying.
Comment 9 Dusan Balek 2014-07-07 11:01:51 UTC 
Unfortunately, it is hard to do anything without a reproducible test case. Next time you observe the problem, could you please capture a thread dump and profiler snapshot (invoking the 'Profile the IDE' action and waiting for a while) and attach it to the issue? Thanks.
