This error has been seen in JAVA applications on some computers after the Windows desktop theme has bee altered.



Try resetting your windows theme to the default.

1 - Go to Windows desktop, right click, and bring up Properties

2 - Go to Themes tab

3 - Change theme to Windows XP



A similar java.lang.NullPointerException will be issued for other java based applications. See (Xilinx Answer 22813)
