Netsparker identified a version disclosure (Jolokia) in the target web server's HTTP response. Jolokia is an agent-based approach for remote JMX access. It is an alternative to standard JSR 160 connectors. The communication between client and agent goes over HTTP (either GET or POST), where the request and response payload is represented in JSON.
