Comment 2 Svata Dedic 2013-08-20 12:30:56 UTC 
The DeclarativeHintsRegistry.computeHints() collects hints classes from classpath, blocking other parser-aware tasks for quite a long time on classpath scanning. 


From the UI log it seems that the snapshot comes from the middle of the work, not right after IDE start (although ZIPs are only opened for file objects; maybe FOBs were GCed already).

Collecting the files asynchronously and semi-cancelably:
