Issue2313

Observed in Jython 2.7rc2 on Windows 7:

> jython -m test.test_jython_initializer
test_syspath_initializer (__main__.TestUsingInitializer) ... Traceback (most recent call last):
  File "C:\jython\2.7rc2\Lib\test\check_for_initializer_in_syspath.py", line 4, in <module>

I wonder if the path is not passed on correctly whether this might be behind several other problems with import.

This test fails for me on Linux as well when run individually:

I have a pull request to fix this one https://github.com/jythontools/jython/pull/70

It fails on Windows because the path to a class file outside /dist was hardcoded. To remove this, I decided the nicest approach was to create a jar which includes the .java and .class files and also the service definition, which can be picked up to initialise Jython, at startup.

This approach also allows a custom compile directory to be removed from the build script.

I have tested on Linux and Windows with Java 7 and 8 but if anyone else wants to give it a try guess that would be good.

Believed fixed at https://hg.python.org/jython/rev/0a00982f6ea5
