Sorry, the process definition is (I hope it gets it right in this post):

<?xml version="1.0" encoding="UTF-8"?>
<process-definition>
<start-state name="start">
<transition to="a" name="to a"/><transition to="b" name="to b"/> </start-state>
<state name="a"><transition to="xor"/></state>
<state name="b"><transition to="xor"/></state>
<merge name="xor"><transition to="c"/></merge>
<state name="c"/>
</process-definition>

Same exception is also thrown from the process of test case Wfp08MultiMergeTest

[cpob]

It is due to the merge node. They really aren't supported yet (both in the GPD or the database).
