Earlier today I upgraded JetGroovy to the latest (1.5.14891) with no problems.
A while later I upgraded to the just-released 7.0.3 release of IDEA. Upon restarting after that installation, I find that IDEA consumes 100% CPU when a Groovy file is being displayed. Switching to a different file causes the CPU use to subside but switching back to a Groovy file cause the CPU to saturate again. This is not just for the duration of the code analysis, it persists indefinitely.
This does not occur when viewing a GSP file, only a Groovy source file.
OS: Linux (KDE)
