The RA Agent WebService SOAP cannot be started in Non Native mode in case the Java version used is Java 11.
The error that is displayed in the Agent Log and Trace file is:
Error: WSDL file cannot be compiled, please read the documentation how to setup the agent environment correctly.
Nevertheless, the compatibility matrix states that RA Agent 4.5+ is compatible with JDK 11.
Incompatibility with JDK 11 in No Native mode not documented due to the usage of CXF external libraries in No Native Mode.
Release : 12.3
Component : RA WEB SERVICE SOAP
The documentation has been improved to reflect this limitation of the "Non Native" Mode
Note: Unchecking 'Use Native Mode' uses CXF and requires Java 1.8
Additionally, references to the "Web Service Response Parsing" were also removed from the documentation as Test tool is not available for Ra Agent Web Service SOAP, it is only available for Ra Agent Web Service REST.
