Otto Fowler commented on NIFI-6109:
-----------------------------------

the call here
{code:java}
if (!StringUtils.isBlank(commandArguments)) {
    for (String arg : ArgumentUtils.splitArgs(commandArguments, 
context.getProperty(ARG_DELIMITER).getValue().charAt(0))) {
        args.add(arg);
    }
}

{code}

is stripping the quotation marks out.
