Description

I tested Studio plugins in Eclipse Mars RC2. Opening the AttributeType editor takes about a minute with 100% CPU load.

The thread dump show that filling the superior combo widget causes the problem. Probably the Eclipse widget has changed.

This issue is just a reminder to check again with final Mars release.
