Anyone ever tried the Eclipse OpenJ9 VM? I've never heard of it, but it might be fun to see if there's a difference with my various apps and performance in an IDE.
I've just been hearing a lot of fuss about GraalVM, though haven't had time to investigate what's so special about it nor how it might help typical 'enterprise' services and Java apps.
- rjsw 7y agoI have used really old versions of J9 on StrongARM systems, it was faster than the Sun JVM at the time as there was no JIT for the Sun one.
- jm2dev 7y agoI used it as a replacement for openjdk 8, and I was very happy with the results. Keep in mind there are a few attributes that differ, but the documentation was very clear on that.
- pron 7y agoJust note that, while the download page is confusing about this point, the OpenJ9 distribution is not OpenJDK; it's a completely separate project, albeit one that copies much of the OpenJDK code. OpenJDK release notes are largely irrelevant to the OpenJ9 build.
- pjmlp 7y agoYes, as part of Websphere. It was quite good in the past and one of the first to support JIT caching. Never used it after it went open source though.
