EmbeddedPCMapping cannot be cast to PersistableMapping

Tilmann Zäschke Mon, 30 May 2016 06:11:28 -0700

Dear all,

I'm trying to implement the schema for the new Optional test, but I keeprunning into a ClassCastException:

javax.jdo.JDOFatalInternalException: Failed to generate new Mapping oftype org.datanucleus.store.rdbms.mapping.java.OptionalMapping, exception: Failed to generate new Mapping of typeorg.datanucleus.store.rdbms.mapping.java.ObjectMapping, exception :org.datanucleus.store.rdbms.mapping.java.EmbeddedPCMapping cannot becast to org.datanucleus.store.rdbms.mapping.java.PersistableMappingjava.lang.ClassCastException:org.datanucleus.store.rdbms.mapping.java.EmbeddedPCMapping cannot becast to org.datanucleus.store.rdbms.mapping.java.PersistableMappingatorg.datanucleus.store.rdbms.table.ColumnCreator.createColumnsForField(ColumnCreator.java:253)atorg.datanucleus.store.rdbms.mapping.java.ReferenceMapping.createPerImplementationColumnsForReferenceField(ReferenceMapping.java:487)

    ....

I'm not mentioning 'embedded' anywhere, so I'm not sure where thisassumption of 'embedding' comes from. I do have Fields of type 'Object',but other tests also don't seem to require embedded=false or similar tohandle field of type Object that reference PCs.

I'm also not even sure (or how I can find out) which of my mapping filesare wrong. The error is the same for application-identity anddatastore-identity. It occurs wile calling makePersistent().

I'm using the latest 'trunk' of the JDO TCK.

I also also consistently get the following error, but it seems to be adifferent issue:>> Error copying implementation log file: Source'C:\Users\ztilmann\Desktop\projects\workspace-jdo\JDO\tck\datanucleus.txt'does not exist

Could anyone have a look and tell me what I'm doing wrong? I can alsoprovide if the mistake is not obvious. Code snippets are below.


Cheers,
Tilmann


Code snippet (error occurs in last line in makePersistent):

    @Override
    protected void localSetUp() {
        addTearDownClass(OptionalSample.class);
        insertOptionalSample(getPM());
    }

    private void insertOptionalSample(PersistenceManager pm) {
        Transaction tx = pm.currentTransaction();
        try {
            tx.begin();

            //create a dummy object as target
            OptionalSample dummyPC = new OptionalSample();
            dummyPC.setId(DUMMY_ID);
            pm.makePersistent(dummyPC);
            ...
        }
    }



Here are the schemas:

public class OptionalSample {
    long id;

    Optional<OptionalSample> optionalPC;
    Optional<?> optionalAny;
    @SuppressWarnings("rawtypes")
    Optional optionalNoGenerics;
    Object any;

    Optional<Date> optionalDate;
    Optional<Integer> optionalInteger;
    Optional<String> optionalString;

    ...
}
