Editor doesn't load a class about advancedexpressionfolding HOT 6 CLOSED

Looks like the same problem happens with java.util.Collections class.

I had this same problem with java.util.Collections and grabbing a thread dump after it happens doesn't show any threads doing anything. So whatever caused the editor to not be rendered isn't due to any infinite loops or anything. I also tried adding an extra catch in buildFoldRegions (the main entrypoint to the plugin as far as i can tell) to see if any other exceptions were being throw when this issue happened -- but nothing is being thrown. Just stepping through the debugger a few times doesn't show anything about the execution of buildFoldRegions to be weird. I tried setting the IDEA log4j settings to DEBUG to see if anything popped out there -- but nothing. I'm not a plugin developer so I don't know the next thing to try to narrow down whats going on -- but its easy to reproduce -- just try to open java.util.Collections. It just sits there and spins with no error logged out.

If one class contains the expressions like null != A, the class in a project doesn't open in the Editor.

The Exception is below:

I'll see if i cant replicate that and submit a PR for it

from advancedexpressionfolding.

I tested this on 0.4.1 and Collections opens up now so I would consider closing this

from advancedexpressionfolding.

@steveash I will close this issue for now. Feel free to re-open if you see it again.
