Process instance fails to terminate.

Question

I start a process instance programmatically through a web service call, passing a couple of parameters to the starting instance. But then, when the last activity is completed and the end event is reached, there is a failure. As a consequence, the instance is not ended. The failure is the following:
com.sap.glx.core.kernel.api.TransitionException: An exception occurred while executing the script "_Approvazione_Vie_Aeree:END_CONTROL_EVENT_End(
      com.sap.glx.adapter.BPMNAdapter:Token_0_Approvazione_Vie_Aeree_84bb2f9ca021a18a7f0398d219d89556 token,

Any help will be appreciated.

Hi Oliver,
thank you for your kind reply.
The stack trace I posted is all what is available from the place where I got it (Operation Management>Processes and tasks>Manage processes).
But looking in the general log, I found much more trace information!! At the very end I found the following:
Caused by: com.sap.glx.core.kernel.api.TransitionException: Cannot instantiate abstract SDO type commonj.sdo:DataObject.
at com.sap.glx.core.internaladapter.typeregistry.TypeRegistryImpl.instantiateSDO(TypeRegistryImpl.java:113)

... 12 more
Hope this is helpful.
Livio.
