This article was previously published under Q307496 SYMPTOMS
If your Java applet depends on downloaded .cab files, you may receive the following error message when you try to download the .cab file:
Skipping CAB: YourCabName.cab
due to java.lang.NullPointerException
Code that depends on this .cab file may not run properly and may cause other exceptions that follow this error message in the Java Console window of Microsoft Internet Explorer.
To see this error message, you must click to select the Java console enabled (requires restart) check box on the Advanced tab of the Internet Options dialog box in Internet Explorer.
CAUSE
The Microsoft virtual machine (Microsoft VM) download page includes the following instructions:
If you have run any Java applets in the current browser session, exit and restart the browser. Return to this page to continue with the download procedure.
If you ignore the download instructions and install Microsoft VM in a browser session where an applet has already run, the Microsoft VM installation may be corrupted. This occurs because Microsoft VM components may be in use, and the components cannot be updated when they are in use. As a result, you receive the error message that is mentioned in the "Symptoms" section the next time you try to download .cab files.
For more information, visit the following Microsoft Web site: RESOLUTION
To work around this problem, reinstall Microsoft VM in a browser session that has not previously run any Java applets.
STATUSThis behavior is by design.
