If we add two types having the same name using the following code:

dynClass1 = dynamicClassLoader.createDynamicClass("typename");
typeBuilder1 = new JPADynamicTypeBuilder(dynClass, null, "tablename");

dynClass2 = dynamicClassLoader.createDynamicClass("typename");
typeBuilder2 = new JPADynamicTypeBuilder(dynClass, null, "tablename");

dynamicHelper.addTypes(false, false, typeBuilder1.getType(), typeBuilder2.getType());



Then the addTypes() method does not throw an exception to report a conflict. However when we try to call executeQuery() later on we get a NullPointerException at that point on the following line:
at org.eclipse.persistence.internal.dynamic.ValuesAccessor.setAttributeValueInObject(ValuesAccessor.java:58)

Instead the addTypes() method should report a configuration problem to ease debugging.

Reproducible: Always

Steps to Reproduce:
1.Create two dynamic types having dynamic classes with the same name and pointing to the same table.
2. Add the two dynamic types to the same dynamicHelper.
3. The addTypes() method does not throw an exception.
