Re: 2.7.0 "final release" non-functional on Windows?

Mike,

JAVA_HOME must be set such that %JAVA_HOME%\bin\java.exe is the Java
executable. See this bug: http://bugs.jython.org/issue2346 It is important
to note that some other possible settings for that environment variable do
not work. Also it is important to set JAVA_HOME exactly per what Windows
expects in terms of quoting, etc:

set JAVA_HOME=C:\Program Files\Java\jdk1.7.0_55

but not

set JAVA_HOME="C:\Program Files\Java\jdk1.7.0_55"

(Not at all the same!)

The easiest way to debug these problems is with jython --print

What you are seeing here is the Jython launcher (jython.exe), as wrapped
with PyInstaller, is unable to find the java.exe - and that java.exe must
be Java 7. The whole thing about
"Z:\jythondev\jython27\src\shell\build\jython\out00-PYZ.pyz\subprocess",
is due to the fact that I built jython.exe on my Z: drive, which mapped my
OS X homedir onto my VMWare install of Windows 8.1. out00-PYZ.pyz refers to
some internal scheme used by PyInstaller.

We need to complete the release notes wiki update I mention on that bug!
And of course fix that bug so it provides a better error message and
possibly can recover in certain cases.
