Integrated web services server changes
Java™ 7 is no longer supported by the integrated web services server. The default JVM on IBM® i 7.4 is IBM Technology for Java 8.0 64bit (option 17). The Java runtime version for the integrated web services (IWS) server will automatically be changed to run on a supported version. To ensure IWS servers start successfully, ensure that Java 8 64bit is installed.
