There are several active hotspot and JDK development repos and
people seem to be confused about where to push changes to.
Here's a brief reminder/summary of the process and hotspot repos:
In general hotspot changes are usually pushed to a hotspot specific
in those repos changes go through hotspot specific nightly testing
We then take snapshots of those repos in a weekly or so basis, run
through PIT, usually on weekends,
and then push them to the targeted JDK master repo, except for jdk9,
in which case it is pushed to the jdk9/dev repo.
For hotspot developers, in a nutshell, the general process is:
(1) Mark the bugs appropriately according to the development phase of
the targeted JDK
- For instance, 7u60 is in RDP2 now, so bugs should be marked
appropriately and approved
before changes can be pushed to the hotspot repo.
(2) Get peer reviews: usually via email to the appropriate hotspot-dev
For backports, if the patch applies cleanly, indicate that in the
request for review,
so that it can be expedited
(3) Once changes are peer reviewed, push the change to the appropriate
hotspot repo VIA JPRT
(4) DO NOT NEED to get approval to push to master, as non hotspot
as that will be requested by the gatekeeper before pushing the snapshot
to the master repo.
Note, except for jdk8, all hotspot bugs should be filed against the
targeted JDK version
the bug is destined for. Hotspot JDK8 bugs should be filed using hs25 as
Here's is the summary of the currently active Hotspot development repos
and the target jdk releases:
note, all these repos are full JDK forests, so fixes that require
pushing tightly coupled
hotspot and non hotspot changesets should be pushed through these repos.
Please give me a heads up if you plan to do so.
JPRT is not available to external developers, so if you do not have JPRT
please contact me once changes have been peer reviewed and are ready to
to hotspot repo.
Please do not hesitate to contact me if you have any question.
