User Comments:
GUEST: Restarted computer
Started only netbeans
Takes up 4-500MB RAM and 60 - 98% CPU immediately
Stayes like this with task scanning, checking for external changes ++ for several minutes
Repeats itself when starting it, while using it, when not using it

GUEST: 1 jsp open, just opened the program and did nothing. Just a lot of task and project scanning without stop. Uses 500MB RAM and 100% CPU.

Very slow creation of java embedded source in indexing thread by web.core.syntax.JSPProcessor which processes also included files. Finally blocked by TaglibParseSupport.getCachedParseResult() waiting for the jsp parsing thread.

As last report is from 7.1 I'm closing the issue as fixed
