2.7.2 does not search modules in current directory when called with -m option.  These modules are loaded on jython console and '-c' option.

    $ ls mymodule/
    __init__.py  __main__.py
    $ java -jar /path/to/jython/jython-standalone-2.7.2.jar -c 'import mymodule'
    (no errors)
    $ java -jar /path/to/jython/jython-standalone-2.7.2.jar -m mymodule
    /path/to/jython/bin/jython: No module named mymodule


I found that when jython is called with -m, it does not have current directroy ('') unless explicitly specified with JYTHONPATH.

    $ pwd
    /home/user/jythontest
    $ java -jar /path/to/jython/jython-standalone-2.7.2.jar -c 'import sys; print(sys.path)'
    ['', '/path/to/jython/Lib', '/path/to/jython/jython-standalone-2.7.2.jar/Lib', '__classpath__', '__pyclasspath__/']

    $ java -jar /path/to/jython/jython-standalone-2.7.2.jar -m site
    sys.path = [
        '/path/to/jython/Lib',
        '/path/to/jython/jython-standalone-2.7.2.jar/Lib',
        '__classpath__',
        '__pyclasspath__/',
    ]
    USER_BASE: '/home/user/.local' (exists)
    USER_SITE: '/home/user/.local/lib/jython2.7/site-packages' (doesn't exist)
    ENABLE_USER_SITE: True

    $ JYTHONPATH="." java -jar /path/to/jython/jython-standalone-2.7.2.jar -m site
    sys.path = [
        '/home/user/jythontest',
        '/path/to/jython/Lib',
        '/path/to/jython/jython-standalone-2.7.2.jar/Lib',
        '__classpath__',
        '__pyclasspath__/',
    ]

On 2.7.1, `-m site` shows current directory as the first item of sys.path.

    $ java -jar /path/to/jython/jython-standalone-2.7.1.jar -m site
    sys.path = [
        '/home/user/jythontest',
        '/path/to/jython/Lib',
        '/path/to/jython/jython-standalone-2.7.1.jar/Lib',
        '__classpath__',
        '__pyclasspath__/',
    ]
