Description of problem:
While other changes done through external means (as in not through DM but pushed from outside through Git) are visible in the DM, renaming a pojo is not reflected.

By renaming, I mean renaming the file and substituting the new name in all relevant places in the file (class name, constructors).

Version-Release number of selected component (if applicable):
BPMS 6.0 CR1

Steps to Reproduce:
1. Create a new Data Object in the Data modeler.
2. Clone the git repository, rename the file, replace all occurrences of old class name in the file, commit and push.
3. In the Data modeler, change something on the old Data object/class and save.

Additional info:
And this time I'm even using ssh when cloning the repository (bug 1001561 comment 27).
