---------------------------------------------------------------------

I attempted to follow your instructions and done a test case which use .obj 
files (see patch COLLECTIONS-363-obj-test-fix.patch attached). I'm also open 
for any suggestions about making it better.

I wonder why splitmap.TestTransformedMap extends BulkTest, but not a 
AbstractTestObject like all other containers.

>     ByteArrayOutputStream bytes = new ByteArrayOutputStream();
>     ObjectOutputStream out = new ObjectOutputStream(bytes);
>     out.writeObject(map); // fails with java.io.InvalidClassException:
