Wade Chandler commented on NETBEANS-45:
---------------------------------------
I'm curious if you look at the attached file
cnd-csm-core-parser-queue-waitready.log what the significance of those are. At
the moment, I'm not experiencing the situation I mentioned, and no thread dump
I have created shows ParserQueue.waitReady. In all of those others, taken
during such times, those stacks are there. I have the full NB installed, but
when these issues have been occurring I have not had any C++ projects opened,
nor had I any opened during those particular runs of the IDE. I have not looked
at that chunk of code yet to see what it is locking on, but at the moment is an
anecdotal observation that appears related.

> Often times when editting a single file, code completion blocks for an
> extensive amount of time which makes code completion practically unusable.
> Looking at the threads of the IDE, code completion and parsing seems to be
> blocked by the attached thread (holding a lock).
> Note that I do not do anything but edit a single file and this happens
> frequently during editting even though there are no external changes.
