I think the root of the problem, and it is not specific to platform, is that the environment in which Jython runs as a sub-process is not quite the same as it is at the prompt. We could give a hint about JAVA_HOME not being set, if we can detect that it failed, or perhaps unconditionally (although not in a way that pollutes output when Jython itself is used in a script).Īlso, Apple-specific features are difficult (for me) to test.

Rather than hide a use of this magic inside our own (the launcher), it seems safer for it be explicitly performed by the user.

$(whatever) means run whatever and take stdout as the value (doesn't it?), so /usr/libexec/java_home is a script that does some magic to give you a value to assign to JAVA_HOME.

When trying to setup my project to use Jython, I need to setup Jython as an available 'Python SDK'. Is the command line Java the same that IntellJ uses?

Java -jar /usr/local/Cellar/jython/2.7.2/libexec/jython.jar brings up the jython command line

That's good so the problem is 'solved' by removing the memory option.
