Hmm..
I'm looking at the source and I see the following mapping:
@OneToMany(cascade = CascadeType.ALL)
@JoinColumn(name = "processId")
@MapKey(name = "name")
private Map<String, VariableInstanceInfo> variables = new
HashMap<String, VariableInstanceInfo>();
That makes me think that there is a join column called processId between
VariableInstanceInfo and ProcessInstanceInfo.
