Description of problem:
It is not possible to access any REST endpoint when you deploy the application on WebLogic 12.2.

Version-Release number of selected component (if applicable):
6.3.0 DR1

Steps to Reproduce:
1. Deploy business-central.war on WebLogic 12c R2
2. Try to access any REST endpoint

Actual results:
Not Found

Expected results:
Correct results according to the URL used.

Additional info:
This issue is not only reproducible on BPM Suite 6.3 but can also be found when using 6.2.0 GA. We noticed it when WebLogic was updated from 12.1 to 12.2. It is probably caused by Jersey version update:
