NetBeans-JavaFX-Soma: #69

  Product Version         = NetBeans IDE 6.8 (Build 200912041610)
(#ec9be6a6486c)
  Operating System        = Windows XP version 5.1 running on x86
  Java; VM; Vendor        = 1.6.0_15; Java HotSpot(TM) Client VM 14.1-b02; Sun
Microsystems Inc.


I created the MediaBox sample and run it.
After that I cleaned the project and run it.
The project did not run with the message "Wait Classpath Scanning"
but class path was not scanned at that moment.

After that I prees the close button on the IDE and IDE Hanged.

Comment 7 J Bachorik 2010-01-04 05:41:43 UTC

Attempted to fix in http://hg.netbeans.org/javafx/rev/6c5faa31679b

The algorithm is sped-up and it uses an iterative rather than a recursive approach. According to my measurements it yields cca. 80% time savings but I would like to ask the reporter to confirm.
