1. Launch Eclipse
2. Load jrxml file
3. Double click a text field (don't know if other objects behave the same)
4. Hang with java process using 100% CPU for about a minute
5. If I clicked around during the hang, UI catches up after it's no longer hanging.
Only happens the first time. Sometimes the hang starts before double-click has begun the edit, sometimes edit mode kicks in after hang. Not sure if this is exclusive to Jaspersoft plugin or would happen e.g. when editing Java servlet, as I use Eclipse primarily for Jasper Reports.
