Problem Description: Getting error 'Assertion Failed WExpression: Window !=(ixobj *)0" on Oracle Forms 10.1.2.0.2 version

Symptoms

1. Following C++ Runtime Library error occurs on the Application Server:

Assertion Failed! Program: ...\oracle\product\10.1.2\asmid_1\bin\frmweb.exe File: C:\forms\1012\src\if\iff\ifrlf.c line:nnn

2. If any question on the dialog error box is answered the OS completely crashes.

3. Problem happens when using Java plug-in. No reports of it occurring with JInitiator.

4. When the error occurs there is no impact on users. (Unless the dialog box is responded to causing the Application Server to crash).

5. The error cannot be traced to any user activity.
Cause :

The C++ Runtime Assertion Failed message is a low level error message. The failure simply means that a variable in the C++ code that was 'asserted' to have a certain value or range of values failed the assertion. This is the reason for the error message, but the high level cause in this particular situation has yet to be determined. There is more than one high level cause for this type of failure


Solution:

For some customers, Oracle has found that the following has resolved the issue:

1. Upgrade to the latest Sun JRE Plug-in version for the Forms client. See -> 10gR2 Statement of Direction http://www.oracle.com/technology/products/forms/htdocs/10gR2/clientsod_forms10gR2.html
2. Apply the latest Forms Focus patch for the Forms version.
