Description

Expanded the provide test case transitions-01.xml to include as childern of the element <parallel id="thirties_parallel">:

<onentry>
<log expr="'Entering thirties_parallel'"/>
</onentry>
<onexit>
<log expr="'Exiting thirties_parallel'"/>
</onexit>

Running the test case will now result in NPE when attempting the log action.

because the parent of on OnEntry and OnExit objects is null.
