Forms :: Oracle 9i Errors On Startup?

We have an application that uses Oracle Forms 9i AS R2 that has been running happily for many years. There are two servers that run the client side application and provide the users with access to a single database. Two weeks ago one of the two servers started expperiencing issues, then yesterday the second server started experiencing issues also. The problem appears to relate to the Java component of the service. Typically what happens is that the user runs a batch file that starts the following java command:

C:OraHome1jdkinjava -Dorg.omg.CORBA.ORBClass=com.inprise.vbroker.orb.ORB -Dorg.omg.CORBA.ORBSingletonClass=com.inprise.vbroker.orb.ORB -Doracle.security.jazn.config=C:OraHome1j2eeOracle9iDSconfigjazn.xml -Doracle.home=C:OraHome1 -DORACLE_HOME=C:OraHome1 -jar C:OraHome1j2eehomeoc4j.jar -userThreads -config C:OraHome1j2eeOracle9iDSconfigserver.xml

This should start a service that listens for connections on port 8888. Internet Explorer then fires up and establishes a connection to the listening port. Unfortunately we never get that far. We receive the following error and the Java service never starts so the IE conection fails to connect to the service on port 8888. unexpected exception has been detected in native code outside the VM.

Unexpected Signal : EXCEPTION_ACCESS_VIOLATION occurred at PC= 0x6d3f1992

We are unable to locate the function name symbol for the error just occurred.
