Describe the issue
When Titan returns an error, like something is wrong with the metadata, we use to get a CmisConstraintException for example "SEAL00222:Error mapping value on existing ValueList.". With the 7.9.1 code (+JWT adjustments) we get a CmisConnectionException :
caught exception: (CmisConnectionException) Cannot access "xyz": (CmisConnectionException) Cannot access "null": Conflict
We should get the CmisConstraintExceptions to be able to see what is exactly wrong.
