JavaAWT: Assertion failure



Hello,

Since I updated to Java 1.4.2 Update 1 on my PowerBook 1,5 Ghz (Mac OS
10.3.5) i get java.lang.NullPointerExceptions when i use Jbuilder X
Foundation. I already posted to Borlands JBuilder Macintosh Newsgroup, but
the had no solution for my problem and refered to this list.
The new 1.4.2 Update 2 didn't help to solve the problem.
The Problem seems to concern Java native code in the AWT. I get the
following error messages when i start JBuilder:

Exception in thread "AWT-AppKit" java.lang.NullPointerException
JavaAWT: Assertion failure: Java exception thrown
JavaAWT: File src/macosx/native/apple/awt/util/AWTException.m; Line 40

When i try to open a file or a project JBuilder hangs after the JFileChooser
dialog is displayed. After that i can only kill the Jbuilder application.
Is there a possible solution to this problem?

Best regards,

Daniel Westhoff
