jythonc generates a .java file that ends up containing methods
marked as deprecated in newer JVMs,  The message is just a warning about
that and is otherwise insignificant.

jythonc issues this message.  -deprecation is not a jythonc option, it is
instead a javac option. Jythonc rightly gives up when it encounters
unknown switches.

see above.

honc?

jythonc allows specifying compiler options with the -J switch.  In other
words, you just add a -J before any java compiler options. Try:

    jythonc -J -deprecation tryJythonSample.py
