L3 - Default Steps to reproduce:
- create a process application with a process
- that process contains two service tasks (x and y, whereby x is executed before y)
- the service task x stores an object value as a variable foo
- the service task y accesses the variable foo
- deploy the process application to any container (e.g. tomcat)
- start and finish a process instance of the given process
- restart the finished process instance whereby it should be restarted after service task x
Observed Behavior:
- A context switch into the process application is not performed during restart, so that
- the deserialization of the object value fails, with the following exception
Cannot deserialize object in variable 'foo': SPIN/DOM-XML-01028 Cannot deserialize '[foo: null]...' to java class 'org.camunda.bpm.example.invoice.Foo'
- and the execution of service task y fails with the following exception:

- the deserialization of the object value fails, with the following exception
Expected Behavior:
- A context switch into the process application is performed, so that
- the deserialization of the object value succeed without any exception
- the execution of service task y succeed.
