Customer has middleware code that dynamically generates servlets but they are seeing the following crashes on both the Client and Server Hotspot VMs on JDK 1.3.1_03, JDK 1.3.1_04 and JDK1.3.1_05 on Windows 2000. This servlet
runs fine as a testcase but thru the customer's app servlet the behavior is different.

Error Message and Stack Trace are below
