Environment (Required on creation):

Reproduced on Automation Platform 7.16.0-SNAPSHOT and Apache Tomcat 9.0.43 distribution via Arquillian.

Description (Required on creation; please attach any relevant screenshots, stacktraces, log files, etc. to the ticket):

exception-stack-trace.txt

Steps to reproduce (Required on creation):

1. Deploy a process application with a custom java class org.pa.MyPojo and a process with a waiting state
2. Start a process instance
3. In Cockpit, set a variable foo via batch operation to the previously started process instance with the following properties:
   • Type: Object
   • Object Type Name: org.pa.MyPojo
   • Format: application/json
   • Value: {"name": "myName", "prio": 5}

Observed Behavior (Required on creation):

The batch operation cannot complete with the following exception:

Cannot deserialize object in variable 'foo': SPIN/JACKSON-JSON-01007 Cannot construct java type from string 'org.pa.MyPojo'

See the full exception-stack-trace.txt.

Expected behavior (Required on creation):

The batch operation completes successfully.

Root Cause (Required on prioritization):

The variable foo is deserialized in BatchSetVariablesHandler. However, in this context the org.pa.MyPojo class is not accessible.

Solution Ideas (Optional):

1. Don't deserialize variable in BatchSetVariablesHandler; instead, retrieve the serialized value from the database and set it to the process instance
2. Switch into the context of the process application
