Description

Consider the following code snippet from test DataSourceReferenceTest:
--------------------
Referenceable refDS = (Referenceable) ds;
Reference dsAsReference = refDS.getReference();
String factoryClassName = dsAsReference.getFactoryClassName();
ObjectFactory factory =
(ObjectFactory) Class.forName(factoryClassName).newInstance();
Object recreatedDS =
factory.getObjectInstance(dsAsReference, null, null, null);
---------------------

When ds is a ClientDataSource40 (i.e. when running with jdk16), recreatedDS is null.

Note, that this showed up only after converting the test to junit, because the original test hardcoded the ds to be a ClientDataSource. I confirmed this not to be related to my changes for DERBY-2296 (which prompted me to convert the test), by backing out my changes to ClientBaseDataSource and client/am/Connection and rerunning the test (needed some minor adjustments of expected values table/array).
