Description of problem:
After importing a jar to project - as dependency - and rebooting server, the jar is no more listed in project's dependencies.

Version-Release number of selected component (if applicable):
BRMS-6.0.0.ER2

Steps to Reproduce:
1. upload jar into Authoring -> Asset repository
2. add this jar to your project's dependencies (via 'Add from repository' button)
3. logout, restart server, login
4. check your project's dependencies - there is no such jar. Add it from repository once more - you've got 2 dependencies on the same jar.

Additional info:
It seems the jar didn't disappear completely - its classes were available in data modeller, but it vanished from Project screen -> Dependencies.
Nothing interesting in the server log
