Description of problem:

During startup, the logs show that a NullPointerException is thrown when a process definition (asset-management, I think?) is being processed.

How reproducible:

Always.

Steps to Reproduce:
1. Start up BPMS or kie-wb.

Actual results:

Multiple NPE's are shown being thrown in the logs.

Expected results:

No NPE's in the logs.

Additional info:

While no tests are currently failing, I think it's important to fix this because it's obviously a bug and the impact is unknown.

Furthermore, this bug has been found and fixed on the 6.3.x and master branches and it only needs to be backported.
