Updated JDK Support

Heroku now offers beta support for OpenJDK 7, as well as an updated version of OpenJDK 6. Support for both JDKs are available in a new buildpack. OpenJDK 6 is still the default, but the version has been increased to u25 from u20 -- changes for u20-u25 can be found on Oracle's changelist blog. OpenJDK 7 can be enabled by configuring your pom.xml. Currently, only maven builds are supported with this update.

This update has no impact on any running applications. If you choose not to use this buildpack, your applications will continue to use OpenJDK 6u20.
