Jython to import "identically named" Java files residing in different directories

Question

I am to use Jython to import two supposedly identical java files for comparison. The comparison is made on the basis of returned values, signatures, and constructors (This works fine, though the problem is in the import). One file resides in the submission folder and the other in the solution folder. The problem is the following,

When I run the following code,

    sys.path.append('Solution/')
    import GeometricShape
    sys.path.pop()

    sys.path.append('Submission/')
    import GeometricShape    <---- the imported module is the same as the one above
    sys.path.pop()

the second imported GeometricShape is of the one in the solution folder, whereas it should be of the submission folder. Deleting the module by del(sys.modules["GeometricShape"]) would still keep the first GeometricShape in memory somehow. imp.load_source doesn't work because it is not a python source file. Creating __init__ in the directories and importing the modules as from Solution import GeometricShapes doesn't work, for I get the error below,

java.lang.NoClassDefFoundError: Solution/GeometricShape (wrong name: GeometricShape)

Is there a solution to this?
