Error description
Error Message: WARNING : OutOfMemoryError possibly caused by 2147483416 bytes requested for object of class 000000003001BD00 from memory space 'Generational' id=00000100105C72F0 Cause of thread dump : Dump Event "systhrow" (00040000) Detail "java/lang/OutOfMemoryError" "Java heap space" received .

Problem summary
OutOfMemoryError is thrown from CDRReader.readBytesForString when receiving more than 2GB allocation request.
Problem conclusion
CDRReader.readBytesForString method is modified to reject the requests greater than 2GB. Now, when CDRReader.readBytesForString requests 2GB or greater from the Java Heap a MARSHAL SystemException is thrown rather than attempting the allocation of 2GB which could result in the JVM throwing an OutOfMemoryError. The MARSHAL SystemException output will include request details and the stack trace. . This APAR will be fixed in the following Java Releases: 8 SR6 FP5 (8.0.6.5) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
