[BUG-12013] Concurrent Modification Exception on project load

I am getting a ConcurrentModificationException when trying to open a project after installing the nightly build. It seems to pop up when it tries to start the perspective module.

To clarify I’m trying to open the designer.

Can you click full and give us the whole stack trace?

Looks related to the changes made to get the Perspective module to load. I’ll have a fix up shortly, should hopefully get merged in and into the next nightly.
