Description of problem:
This is detected when running bpm-example-app ER1.
For some reason, the productized artifact com.sun.xml.bind:jaxb-impl:jar:2.2.5-redhat-5:compile does not embedd with 
1)com.sun.istack:istack-commons-runtime
2) com.sun.xml.txw2:txw2
which will cause the error when running the bpm-example-client jar. 
However the community version of com.sun.xml.bind:jaxb-impl does embed those classes.

I think the solution will be add those package in bpm-example assembly code explicitly.

The stacktrace:
