Issue222876

With a classpath containing classes from the same package in both a directory
and jar file (in that order), 'import' only checks the first one (the
directory).

- set the classpath to include only the current directory, followed by one jar
file (order is important), eg. CLASSPATH=.:kFQueue.jar
- identify two classes which exist in the jar file, eg.
com.pplus.util.Comparator and com.pplus.util.BooleanComparator, and:
  - create a matching directory structure, eg. com/pplus/util
  - copy the _first_ class file to that directory
- now start JPython, import the first class, _then_ import the second class -
this will fail. Eg.

  JPython 1.1+07 on java1.3.0 (JIT: null)

  >>> from com.pplus.util import Comparator
  >>> from com.pplus.util import BooleanComparator
  Traceback (innermost last):

  AttributeError: instance of 'org.python.core.PyJavaDirPackage' has no

    'BooleanComparator'

new load design avoids this naturally.
