JsonPath Match and JsonPath RegEx Match assertions fail with SoapUI 5.7.0 (and worked with v5.6.1)

Hi, I'm totally new to SoapUI and I'm taking over the integration tests of a colleague who left the company.

Our security department requires us to use log4j 2.17 which is embedded in SoapUI 5.7.0. This requires us to upgrade our current version of SoapUI v5.6.1.

I tested few users scripts with SoapUI 5.7.0 and all run smoothly but the few integration tests fail. I've been searching for days without finding the solution to this issue. The issue is not related to our code since command testrunner.sh fails with the exact same parameters (see below).

I first run the mockservicerunner:

$ mockservicerunner.sh -m"REST MockService" -p 58475 test/integration/monitoring/soapui/soapui-project.xml

I know that there's a bug with "JsonPath Match" assertions in SoapUI 6.7.0 but replacing them with " XPath Match"  does not solve the pb.

Find attached the entry files.

Any help would be greatly appreciated.
