[Jython-bugs] [issue2569] jython launcher fails on Windows if JAVA_HOME is set

[James M. <re...@bu...>]

New submission from James Mudd:

Trying to execute the jython using the exe or python launch script on Windows fails if JAVA_HOME environment variable is set

Microsoft Windows [Version 10.0.14393]

C:\Users\user\Desktop\dist\bin>jython.exe
Jython 2.7.1rc1 (, Mar 13 2017, 08:51:49)

Failed to execute script jython --------- Fails

Running as admin doesn't help. I think the problem is when JAVA_HOME is set then cmd used to invoke java is the full path C:\Program Files\Java\jdk1.8.0_121\bin\java and python doesn't seem to have permission to launch this. However when JAVA_HOME is not set the cmd used is just java and it relies on java being on the path, it seems python can launch this?

Any ideas for a fix? Or others give it a try and see if it fails for you?
