User Comments:
Legoman2803: The Javadoc windows wants to load. 28 sec black screen (Repaint manager).
May be you set the javadoc window in a thread so that the main window thread does not get blocked by the javadoc.

Self-sampler data shows that the complex html document is rendered by AWT. Since this is all done by JDK, we will not be able to improve it, but you can try to use latest JDK, latest NetBeans and use 64bit JDK instead of 32bit, you are currently using.
