Error description
In IBM Business Process Manager (BPM) V8.0, under high load, exceptions can occur when different sessions try to access to the same coach. The probability of seeing these exceptions increases as the load and the size of the business objects that are used in the coach increase. You might see a stack trace that is similar to the following stack trace in the SystemOut.log file: java.lang.NullPointerException: at com.lombardisoftware.core.TWObject$SerializedForm. access$1600(TWObject.java:182) at com.lombardisoftware.core.TWObject. setActivationVersioningContext(TWObject.java:1268) at com.lombardisoftware.core.TWObject. setActivationVersioningContextOnObject(TWObject.java:1280) at com.lombardisoftware.core.TWObject. setActivationVersioningContext(TWObject.java:1270) ... .------------------------------------------------------ This can also result in data corruption that might cause this exception, java.io.StreamCorruptedException: invalid type code: 00. The error logged will have this as the most deeply nested exception. [6/16/15 8:51:00:773 EDT] 000007a5 wle E CWLLG2015E: An unexpected runtime exception occurred. See exception for more details.

Local fix
Problem summary
The problem is caused by race conditions that happen within a small number of statements and, therefore, are difficult to enforce or to reproduce.
