WildFly 12 Final is now available for download!

EE8 Capabilities & New Release Model

This is our first release following our new quarterly delivery model. As part of this plan, we are delivering EE8 functionality in fully completed incremental chunks, as opposed to waiting for everything to finish in a big bang reelase. WildFly 12 makes significant progress on this front, adding support for the majority of the new standards:

By default WildFly 12 launches in EE7 mode. In order to use these new capabilities you have to enable EE8 preview mode. This can be accomplished by passing the ee8.preview.mode property during startup:

./standalone.sh -Dee8.preview.mode=true

Alternatively, this can be achieved by launching the server using the new standalone-ee8.xml configuration, which simply includes the property in the config.

./standalone.sh -c standalone-ee8.xml

The CLI can also be used to modify the existing configuration to add this property. For example:

embed-server --admin-only=true
/system-property=ee8.preview.mode:add(value=true)
stop-embedded-server

Other Notable Items

  • WildFly 12 includes a new thread pooling strategy that reduces the number of threads active at any given time, which helps conserve system resources.

  • MicroProfile REST Client 1.0 is now supported

  • Java 9 compatibilty has been improved

  • CLI scripts can now take advantage of loops with variables

  • WildFly Documentation is now in asciidoc, and part of the source tree
