Build 070728. After a few minutes editing in a large project, semantic highlighting stops working and code completion always says scanning in progress. Switching to another file may wake things up for a while, but always the file becomes broken in some way that the parser just doesn't try to process it any more - or at least that is the impression. It appears that using generics heavily makes things particularly fragile. But the situation is really unusable - about 70% of the time, the parser is broken.
Could you please try to make a thread dump when the problem occurs? Thanks.
Raise back when you have steps to reproduce and stack trace.

In the TDs, the code completion is working, so it seems strange that any part of the system thinks that scanning is in the progress. Jan, could you please try to disable assertions in your etc/netbeans.conf? Thanks.

On the stack trace there is running code completion thread, I have no idea why editor thinks the background scan runs. Anyway I am not able to reproduce it. Tim can you try it with current build. If you are able to reproduce it please attach thread dumps.
I am closing this issue as there is no additional info for a long time - I hope it has been solved then :) Anyway, if you are still experiencing problems with that, feel free to reopen with some additional info that could help. Thanks!
