IDEA attempts parsing entire directory tree of newly attached library source from within EventQueue thread

Created: 07 Nov 07 21:56   Updated: 08 Nov 07 18:08
Component/s: Project Configuration

Environment: Ubuntu Linux

Build: 7,531
Severity: High


 Description  « Hide
I experienced a hang as IntelliJ apparently tried traversing the entire directory tree of an attached library source that I added. The main reason we use library source instead of project source is to avoid such hangs... I don't remember this ever happening in 6.x.

Here's the (reversed) stack trace:

This is not a bug but rather an architectural limitation. This processing has always been performed in the event dispatch thread.
