#16 LTK-Java Required Parameter bug in RO_ACCESS_REPORT Message
I am getting an error saying that the RO_ACCESS_REPORT is missing a required parameter of type EPCParameter. This is what the message looks like:

And this is my stacktrace:

Perhaps the tk doesn't realize that EPC96 is a valid EPCParameter or something.
