Description of problem:

It is not possible to use a repository and projects cloned/installed via REST API.

After installation of a project via REST API:

I have a different problem when I clone the repository and install a project in Business Central. The REST request or any action in Business Central (e.g. start of a process) ends with:

Process Instances failed to start: java.lang.NoSuchMethodError:org/drools/persistence/OrderedTransactionSynchronization.(Ljava/lang/Integer;Ljava/lang/String;)V

However, I believe these are two problems which might have the same cause.

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

How reproducible:

Steps to Reproduce:
1. Clone a repository via REST API
2. Install a project from that repository via REST API
3. Start a process via REST API
4. See all the exception in the server log and on the client side

Actual results:
