2nd attempt at bringing Shenandoah GC to JDK11u: mail.openjdk.java.net/pipermail/jdk-…

Next chapter in the saga "Shenandoah GC in JDK11u": "I can (and did) prove that Shenandoah does not leak anywhere in libjvm.so when Shenandoah is disabled. ... Shenandoah is in-fact cleaner in this respect than any other GC in OpenJDK." 😊 mail.openjdk.java.net/pipermail/jdk-…

Shenandoah GC finally landed in JDK11u! We went a couple of extra miles to ensure that even the most conservative users have no need to worry: we proved that the resulting object files have no traces of Shenandoah code left when Shenandoah is disabled. hg.openjdk.java.net/jdk-updates/jd…

Great write-up by Andrew Haley is aph13 in the blue place 💙 🏳️‍🌈 of the work he and Andrew Dinn did to start a collaborative FOSS port of #OpenJDK to #AArch64, a project which continues to grow. As an addendum to this, I've just pushed the original and still-maintained 8u version upstream for release in 8u292.

JDK 11.0.10 #Shenandoah do not have the concurrent stack walking nor the or SATB flushing, but it offers a reliable low pauses, and another unexpected benefit: - With G1 the used-heap was climbing to ~2GiB or until the Young collection - With Shenandoah the used-heap tops 400MiB

I did some benchmarks while writing an article about OpenJDK's Shenandoah GC 🤩😎

valgrind is a very useful tool for memory leak. I played it with OpenJDK, here is what I found: cr.openjdk.java.net/~zgu/memory_le… I only wish it could scale better, so I can run big apps.

After absolutely amazing 6+ years, I hang up my fedora today. While I am sad to leave such an awesome team, I am looking forward new challenge ahead.

Can not believe it happens in ~20 years old GC: bugs.openjdk.org/browse/JDK-832…
