Trying to use the XML configuration as indicated in the Drools Planner documentation;
"...or a valueFilterClass on the valueSelector:..."
Quick look at the source failed to turn up references. The first mention of this feature is in the 5.5.0.Beta1 Drools Planner documentation (it's also in subsequent versions) - perhaps something has not been committed/merged somewhere?
Full error message:

There may be other issues in this source - apologies in advance.
To recreate:
Using XML configuration, add the following to the Xml (as indicated by the planner document),
<changeMoveSelector> <selectionOrder>RANDOM</selectionOrder> <valueSelector> <valueFilterClass>com.example.MyFilter</valueFilterClass> </valueSelector> </changeMoveSelector>
