Phoronix: Eclipse OpenJ9 0.27 Released For OpenJDK 8/11/16 Alternative

The Eclipse Foundation has released OpenJ9 as the latest version of their high performance virtual machine that continues advancing four years after IBM donated the original J9 code...

"high performance"? For a benchmark site that hasn't tested it, I am not sure.

Proof? Last time I saw OpenJ9 slower than HotSpot.

It's linked from their site -> https://www.eclipse.org/openj9/performance/

it looks like it's slower but smaller

OpenJDK 8/11/16

For a second my dumbass thought that part of the headline was a date.

It was tested on this site. It is slower.

In my experience it is slightly slower in general and up to two times slower on some workloads. Also it is much less stable, including segfaults and bytecode miscompilation. Also tooling is pretty different from Hotspot, mostly Eclipse plugins. On the plus side it really consumes less memory both heap and native.

When I tested it with a large project it was a lot slower than HotSpot, but I'd guess large applications are not a target use for OpenJ9 with it's main focus being fast startup.

Yeah, pretty funny claiming "high performance" when you only have a handful of implementations out there (3, I believe, including this one).

Also, a brilliant move offering Java 16 (non-LTS) support a couple of months before the release of Java 17 (LTS).

How would they support unreleased versions? Besides the LTS part doesn't mean anything. They'll release new OpenJDK versions every 6 months. You'll only get any kind of long term support by buying the commercial build.

"Released" doesn't mean anything in this context, because we're looking at an alternative implementation. J9 would only need to support the same JEPs OpenJDK does.

Enterprises don't touch non-LTS Java, that only supported for 6 months. All non-LTS releases have a big, big problem: they're supposed to be testing releases, but because enterprise won't touch them, they generate very little feedback.

Anyway, it seems I judged them too early, support for 17 is coming this September: https://www.eclipse.org/openj9/docs/openj9_support/
