Description
javax.swing.text.html.ImageView is incorrectly accessing System properties without checking for proper previledges or traping an AccessControlException.
This problem is related to bug #4181905 but a slightly different variant. The offending lines are below.

424--->	s = System.getProperty("awt.image.incrementaldraw");
	sIsInc = (s == null || s.equals("true"));

427--->	s = System.getProperty("awt.image.redrawrate");
	sIncRate = (s != null) ? Integer.parseInt(s) : 100;
	
Line 424 generates AccessControlException in the Java Plugin running JDK1.2FCS-N within IE4. I suspect 427 would do the same if it ever got there.

When you get to testing the bug fix we have JavaHelp test we can run or provide.

EVALUATION ImageView is in bad need of a rewrite, and continues to plague us. The calls being made aren't really needed, and there are better places to store the information. The best fix to this one would be to remove the access to the system properties. This has been ok'd for the next dot dot release. timothy.prinzing@eng 1998-10-17 Removed the use of System.getProperty() for the image refresh rates. timothy.prinzing@eng 1998-10-28
