Jython 2.5.2rc1
Bugs Fixed
+ - [ 1639 ] JBoss 5, vfszip protocol in use for jarFileName in PySystemState
- [ 1660 ] threading module memory leak
- [ 1452 ] pydoc help() function fails because sys.executable is None in stand-alone Jython
- [ 1568 ] sys.stdout.encoding returns wrong value in Windows with Jython 2.5.1 (fixed on Java 6 only)
