Hi,
I've used HermesJMS in SOAPUI for years as part of an automated Continuous Integration pipeline because we use IBM MQ. I've also just tried to upgrade to version 5.6.1 due to the log4j vulnerability and couldn't get Hermes JMS working. Just wasted all of yesterday trying to get Hermes JMS to work, but just hangs when the .bat file is manually invoked. I am not sure why the installer still has it as an option if it's no longer supported!
Hoping now that I can revert back to 5.5.0 and just update the log4j jar file.
