Autoupgrade analyze failing on UTLRP_RUN_SERIAL

Looking to upgrade a 12.2 DB on x86-64 OEL7.4 to 19.4, so I thought I'd give the Autoupgrade utility a try. I'm using the JRE included with 19.4, "1.8.0_201".

As recommended, I started with the "analyze" phase. After encountering an error during the "UTLRP_RUN_SERIAL" check, I downloaded the latest Autoupgrade from MOS 2485457.1. The error format changed, but it's still erring out on the same check with:

2019-10-10 09:38:56.400 ERROR Error occurred while running the dispatcher for job 101
Cause: An execution error occurred when running the database checks or fixups - AutoUpgDispatcher.run
2019-10-10 09:38:56.400 ERROR The dispatcher has failed due to: Error: UPG-1316
[Unexpected Exception Error]

This shows up in the "autoupgrade_user.log" file:

Exception: NumberFormatException
Err message: For input string: "50,50"

...which appears to be a modified version of the standard Java stack trace found in the "autoupgrade_err.log" file.
