ReadyAPI-3.50.0-wargenerator.bat creates war-files which needs javax-libraries

We are using SoapUI with version 5.7 to create a war-file, which should act as a mock-server for SOAP-Requests and which can be deployed into an JBoss/Wildfly-container

After changing our environment to a java17 we got deploy-errors like

java.lang.NoClassDefFoundError: Failed to link io/swagger/v3/jaxrs2/integration/OpenApiServlet (Module "deployment.wsmocks.war" from Service Module Loader): javax/servlet/http/HttpServlet

This is ok for a war-file created by SoapUI, since SoapUI only supports up to Java 16

But when we change to a ReadyAPI-Installation (ReadyAPI-3.50.0) wo got the same error.

Is there any solution for this problem?
