Problem root cause

Bug in the JDK:

Solution or Workaround


Upgrade to Talend version 6.4.1.



Alternatively, this would work if deployed in Runtime by editing etc/org.apache.cxf.http.conduits-*.cfg to remove tlsClientParameters.disableCNCheck (if it's specified) and replace it with tlsClientParameters.useHttpsURLConnectionDefaultHostnameVerifier = true. Also comment out all of the lines starting with tlsClientParameters.trustManagers if the server CA certificate is already in the JVM's own truststore.
