Hi,
When it happens again, either run VisualVM in parallel & monitor, or
take a few thread dumps in sequence (CTRL + \ in console or SIGQUIT
signal). Maybe the thread dumps could lead us to what blocks project
open or takes so much time. File a JIRA issue + attach the visualvm
snapshots or thread dumps. Thanks.

I've hit this exception a couple times now... I'm just trying to open
Gradle projects. Note that the Open Project... dialog takes a very long
time to appear, unacceptably long - tens of seconds.
