Release Process
Right after the update release 8u<release before n> was branched from mercurial forest jdk8u-dev to jdk8u, the The release cycle for release 8u<n> starts . As the very first step, its initial stage in the jdk8u-dev repository will be as soon as the previous release enters its second stage and is confined to the jdk8u repository. The starting point is tagged with jdk8u<n>-b00. At about . Once the previous release has happened, jdk8u-dev begins a cycle of being tagged on a weekly basis - when new changesets have been pushed - and the latest tag is promoted from jdk8u-dev to jdk8u.. The tags have the format of jdk8u<n>-b<build>, where <n> is the placeholder for the update release and <build> is the monotonically increasing double digit build number.
About 6 weeks before its release, or general availability (GA), an update release enters ramp down phase 2 (RDP2) and the current state of jdk8u-dev will be transported to jdk8uenters Rampdown. From that point onwards, the update release is stabilized by only accepting very select fixes in jdk8u. Eligible candidates are fixes that Oracle has brought to their correspondent JDK8 update release, fixes for , such as regressions, high priority issues or and test fixes. Builds from jdk8u will be tagged Tagging again takes place on a weekly basis , - when new changesets have been pushed. The tags will have the format of jdk8u<n>-b<build>, where <n> is the placeholder for the update release and <build> is the monotonically increasing double digit build number. Each tag that gets set in jdk8u will be changes have occurred - but this time, it occurs in the opposite direction, with jdk8u changes being integrated back to jdk8u-dev in a timely manner. At about 2 weeks before GA. At the end of the month prior to the release month, a complete freeze will be anounced announced for jdk8u, allowing the maintainers of the security changes (currently Red Hat) to integrate and test these into the repository and perform final testing of the collected fixes in a secure, internal environment. At the On release day, these the final batch of changes will be merged into pushed to jdk8u and the final tags jdk8u<n>-b<build> and jdk8u<n>-ga will be set. To complete the process, jdk8u changes are integrated back into jdk8u-dev
