I opened http://youtrack.jetbrains.net/issue/IDEA-53150 since it appeared that editing a Groovy file after modifiying imports caused Maia to lockup.
This doesn't appear to be the case but the IDE does indeed lockup within 5-10 minutes or a restart and editing of a Groovy class. This ends up requiring a kill -9 on Ubuntu 9.1.0 to kill Maia (build 585) .
I don't encounter this with a Java class.
Anyone else have this issue?
