Since the 8.0 production release (including the latest 9144 build), IDEA seems to get stuck sometimes with it's code parsing.
Basically, it will start saying some class class does not exist, but it exists on the source path (the last time this happened, IDEA was denying the existing of a class that was actually right there in the same package).
It seems like IDEA's metadata repository about the source base gets corrupted, and then it can't get it clean again.
A full rebuild doesn't fix the problem, neither does a re-start of the IDE.
When it happens (once every day or two so far), the only way I've found to get IDEA working properly again is to shutdown IDEA, delete the system/index and cache directories, then restart IDEA. This leads to a full parse of the source and libraries, which is very annoying.
I can't reproduce it reliably yet, it seems like it happens often when some other error has occurred with the IDE.
Anyone else getting this issue?
