[Help]: -openj9 container not in "beta" anymore - safe to use? #718
-
Controller Version6.0.0.25-openj9 Describe Your Issue or QuestionI've noticed that up until a few days (weeks?) ago, the container images with "openj9" tag were also always mareked as "beta". I know there were some plans to test using openj9 as a more lightweight Java alternative, did something change there? Is this tag ready to use as a substitute for the normal Java version? I'm also asking because I can't see any commits newer than 2 years agoi in the "openj9" branch. Expected Behavior. Steps to Reproduce.

Yeah, so it's probably a little confusing. The beta tagged images for OpenJ9 are actually the beta versions of the controller software but with OpenJ9 for the Java runtime. The OpenJ9 images for the GA versions of the software are there and available for 5.15, 6.0, and 6.1. The only reason I would say that the OpenJ9 images are still in this gray "beta" area is just that it's not the default runtime at this point. I still need to do some further research to see if there is anything that can be done to actually optimize the runtime more than just swapping out OpenJDK for OpenJ9 as I don't think we are getting the full benefits from OpenJ9 as a runtime, like the shared class cache. #373 is still the place for further OpenJ9 discussion - I just currently don't have the free time to do the needed research and testing. |

Okay, makes sense. In my case, I'm, happy to just use the OpenJ9 version as long as the container versioning stays inside "stable" releases (not beta- tag). So when something breaks, I know the alternative runtime is to blame, not the beta release of image itself. |

Yeah, I'll continue to have the latest GA releases available for the OpenJ9. At this point, I really wouldn't say that it's in a sort of a "beta" as much as it just isn't the default Java runtime and may not be 100% optimized. |
