Cannot fetch arguments in commandline when using sikulix.jar version 1.1.4

Code:

import sys

a = []
a = sys.argv[1:]
if len(a) <= 0:
    print "empty"
else:
    print sys.argv[1]

Commandline:
java -jar <path>\sikulix.jar -r <path>\trial.sikuli -- "a"

when using v1.1.3 sikulix.jar (Windows 10 32bit), results is "a"
however when using v1.1.4 sikulix.jar (Windows 10 64bit) results is empty
