it seems that camunda-spin has a problem when a variable is set to null. We try to set a variable (enum) to null, or remove a variable.
Example 1:
1. Start process with process variables
2. Complete task and set one of the process variables to null ( taskService.complete(taskId, map); )
Exception:
java.lang.IllegalArgumentException: SPIN-01001 Parameter 'parameter' is null

Example 2:
1. Start process with process variables
2. Explicitly delete one of the process variables ( runtimeService.removeVariable(processInstanceId, key); )
3. org.camunda.bpm.engine.impl.variable.AbstractVariableStore#removeVariableInstance makes:
variable.delete();
variable.setValue(null);
Question: Why is the entity deleted and in the next line the value is set to null?

In both examples org.camunda.bpm.engine.impl.spin.SpinSerializationType#setValue is called to set null as variable value.
