The end of Java SE 6: How it affects integrated web application server (April 15, 2017)

Perhaps you’ve seen some of the recent Java SE 6 end of support messages from IBM and wondered about the effect on integrated web application server (IAS) for IBM i. In short, public updates for Java SE 6 are no longer available, and the end of support in Liberty (which IAS is based on) is set for September 2017. But what does that mean for your current IAS installations?

End of support for Java SE 6 means you can’t get updates or fixes for Java problems such as security vulnerabilities. Staying on the Java SE 6 level could leave your applications exposed to future issues. To ensure your applications are running in a supported environment for years to come, we recommend moving to the latest Java — Java SE 8. Java SE 7 is also an option, but its support only runs until 2019. You can update the Java version for a server by using the IBM Web Administration GUI for i. Select the server, then click on the Server->Properties link and you will be able to select a Java version from a selection list. If you do not see a suitable version, you will need to install the licensed product that contains the Java version you desire.
