Cause

Unknown

Environment

Linux, Java 8

Diagnosing The Problem

Examine the logs.

Resolving The Problem

Set Generic JVM Arg property "-Dcom.ibm.CORBA.UseSchemaIDR=false" on all Java 8 JVMs where the application is running. Here is the document which shows how to setup this property for WebSphere Application Server http://www-01.ibm.com/support/docview.wss?uid=swg21417365
The property com.ibm.CORBA.UseSchemaIDR when set to false, disables optimized CORBA Marshaling and switches back to the CDR format of writing the data across the stream. (The format used in Java 6.1 and Java 7)
