Recent Java Updates From IBM

in preparation for a java conference, i’ve spent some time catching up on the latest activities in the java community. with java ee’s move to eclipse and projects like microprofile, there are a lot of things going on and there is a lot of innovation. below are some pointers to articles my colleagues have recently published.

licensing

oracle has changed the licensing for commercial use. fortunately, ibm open-sourced openj9, which is available together with the openjdk at no cost from adoptopenjdk , even for commercial use.

more about licensing:

• java licensing has changed, but there’s good news
• free java with paid support: the ibm perspective
• adoptopenjdk: an open java distribution and community you can count on
• java licensing has changed, and you could be affected

eclipse openj9

the code of the open-source jvm openj9 is the same code base used by the ibm sdk for java, which means that it’s enterprise-ready. plus, startup time is 40 percent faster and memory usage is 60 percent lower compared to other jvms, which makes it a perfect fit for container-based workloads.

eclipse microprofile

microprofile allows building cloud-native enterprise microservices. i like especially that mircoprofile-based services can supplement istio functionality, for example, for application-specific fallbacks.

more about microprofile:

• microprofile, the microservice programming model made for istio
• microprofile
• microprofile starter
• write a simple microprofile application
• code pattern: configure your app using eclipse microprofile config
• istio
• code pattern: make java microservices resilient with istio
