+# JVM argumments have prefix JVM.

[jbudorick, 2016/05/09 21:13:40]

Let's try something a little different here:
 - use argparse
 - make callers pass in arguments via either --jvm-arg or --jar-arg (repeated)
 - use that to split instead of prefixes

+jvm_arguments = [ x[3:] for x in sys.argv[1:] if x.startswith('JVM')]

What does this 3 mean?

JVM arguments start with JVM to differentiate between JVM arguments and Jar
arugments. For example, JVM arguments are 'JVM-DXXXX=YYYYYY', but when we
actually pass it to JVM, we take away the JVM tag.

+jar_arguments = [ x for x in sys.argv[1:] if not x.startswith('JVM')]
