[#200404191800, in release 3.6 too; 
j2sdk1.5.0, j2sdk1.4.2_03 too]
When running NetBeans while JAWS screen reader is
on then there is something wrong in the
propertysheet - some actions cause the crash of
Java VM. Here are the steps to reproduce:
1.Install JAWS for windows 5.0
ftp://ftp.freedomscientific.com/users/hj/private/WebFiles/JAWS/j500846demo40.exe
2.Install Access Bridge 1.1 GA
http://java.sun.com/products/accessbridge/
3.Run JAWS
4.Run IDE
5.Open create some e.g. JFrame Form and select
propertysheet
6.Move by arrows/tab through propertysheet
7.JVM crashes - see the attached console content

The previous attachment is for the following scenario in Options dialog:
1.Select some node of the tree
2.Swith to properties table on the right (Ctrl+Tab)
3.Press down arrow (2x)
4.VM crash
Comment 4 _ tboudreau 2004-04-23 16:28:37 UTC 
1.  A JVM crash is certainly not a bug in NetBeans code
2.  The code in question is expecting the table header to be non-null.  Table headers can 
legally be null.  Probably this code is doing something in native code and not testing for 
null first.

There's nothing I can do to fix this and it's not a bug in NetBeans.  File a bug against the 
screen reader.

Tim, thanks for evaluation and giving the clue. The problem is realy
in Access Bridge (the number of issue in BT is 5038340). It works fine
with JDK1.5 Beta2 Build 49.
