How can I set the JVM memory limit (-Xmx option for Java) for my Jython program?
I understand that Jython 2.5 introduces the -J option in order to send options to the JVM:
jython -J-Xmx8000m
However, I have to work with Jython 2.2a0 on java1.6.0_23, which does not have that option.

You could just edit jython.bat(windows) or jython(Linux) and add it.
"C:\...\java.exe" -Dpython.home="C:\..." -classpath "C:\...
to
"C:\...\java.exe" -Xmx1024m -Dpython.home="C:\..." -classpath "C:\...

You could set environment variables JAVA_OPTIONS (for jython < 2.5) or JAVA_MEM for jython 2.5 e.g.:
alias jython1G="JAVA_OPTIONS=\"-Xmx1000m $JAVA_OPTIONS\" /usr/bin/jython"
