Prevent unbounded thread creation during parallel OST generation

[Philip Stennett]

When I try to generate the offline symbol table for my project the IDE crashes and completely closes every time. Plugin and IDEA are both fully up to date.

The root cause is unbounded thread creation when parallel OST generation is enabled. Need to see whether the number of active threads can be capped and, if so, decide what value to use (configurable?).

Philip, would you mind doing two things: 1) send me your idea.log found via Help>Show Log in Explorer/Finder; 2) try generating the OST with parallel processing disabled and see if that works.

[Philip Stennett]

Turning off the parallel processing fixed the issue! I have attached the log which I believe has the error from yesterday anyway in case it helps.

Thanks, Philip. It definitely looks like it's an issue with the thread pool being allowed to grow too large. I'm just using IntelliJ IDEA's built-in thread pooling, so I'll see if there's a way to be more selective with that going forward to avoid this type of situation.

Putting this into the 1.7.3.8 bucket for investigation. If there's an easy way to cap the thread pool size using IntelliJ's thread pooling capabilities, I'll fix it as well.
