Announcing WildFly Swarm 2017.3.3

WildFly Swarm 2017.3.3

Since it’s good to beware the ides of March, we’re releasing 2017.3.3 a few days prior to it. Et tu, Brute?

What’s New?

  • Health API Changes (breaking)

  • Fixing logging bugs introduced in 2017.3.2

What is WildFly Swarm?

WildFly Swarm is the decomposition and reconstitution of the popular WildFly Java Application Server in order to support just enough appserver for microservice type applications.

Each portion of the appserver is referred to as a fraction, which many times maps to a subsystem from WildFly, but also may include other discrete chunks of non-Java EE or WildFly functionality, such as Swagger, or Jolokia.

Health API Changes

The health API moved from org.wildfly.swarm.monitor to Apologies for the changes, but we ran into a bug when health was used with the config-api. To mitigate the problem, the health API had to be relocated into it’s own module and package.
