Subject: GraalVM JIT now integrated into Oracle JDK but still not in
 OpenJDK

Can anyone answer this question? It seems to have been neglected.

This is also the question I want to ask. For a long time, no one seemed to
mention Galahad again.
I'd like to know what else Project Galahad has done besides releasing
GraalVM on the same schedule as OpenJDK and changing Graal's package and
module names?
Is there a schedule for merging Graal into OpenJDK mainline?

Hi Cesar and Volker,

I got some information from other places.

Project Galahad is in progress and they are working on the galahad[1]
branch.
This branch can be built based on openjdk master, and it seems that
conflicts with openjdk master will be resolved in a timely manner.
Those PRs[2] starting with [JDK-xxxxxxx] are part of Project Galahad.

I'm sure they want to commit Graal JIT to the openjdk mainline, but I don't
know why they haven't done so yet.
Maybe they need to solve some other problems before that.

Hi Glavo, thank you for sharing this info.

It?s an unfortunate that things aren?t more transparent.

Will GraalJIT ever be part of OpenJDK? Will polyglot/truffle, native image ?

I?m looking forward to hearing back from you and seeing if my team and I can contribute to making all this happen.

Hello,

my name is Steffen Nie?ing and I'm a software developer from Germany. I've studied Computer Science at the TU Dortmund University and always loved the topics on programming languages and compilation. For 2+ years I am developing web services using Java.

I am excited to participate in maintaining and evolving the Java programming language in this community.
I've found a few small documentation improvements for the Java standard library that led me here and I hope this is a good starting point in participating at the OpenJDK project.

I am now searching for a sponsor to get started. Should I ask at the jdk-dev mailing list while discussing the changes or is sponsoring typically asked for on this mailing list?

Cheers,
Steffen Nie?ing

Hello Steffen,
For the Java standard library, most of the discussions happen on core-libs-dev at openjdk list. The jdk list is usually for governance that applies to all of the JDK.

Since you have improvement proposals, you can start either with a mail to the core-libs-dev list or a submission to bugs.java.com - note the latter creates an issue but almost certainly attracts less attention. If you have questions, asking in a list is almost always better than submitting a particular enhancement. And I am willing to answer.

For sponsoring, if your proposal in core-libs-dev is sensible, OpenJDK authors may create a JBS issue for you (which is exactly what bugs.java.com does, except that takes longer). And whoever is willing to create an issue for you is usually willing to review and/or sponsor.

Before you start your contributions, be sure to check out the guide - https://openjdk.org/guide/ For example, you must sign the Oracle contributor agreement.

Regards, Chen Liang
