recreating a datasource using javax.naming.Reference from a ClientDataSource40 fails

• Key: DERBY-2559
• Type: Bug
• Status: Resolved
• Resolution: Fixed
• Priority: Major
• Assignee: Kristian Waagan
• Reporter: Myrna van Lunteren

• Affects Version/s: 10.3.1.4, 10.4.1.3

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).
