Shenandoah 8u252+ release candidate

[Aleksey Shipilev]

Hi,

We are pleased to announce that most of the recent bugfixes and improvements have been backported to
Shenandoah 8u tree. That tree is based on upstream OpenJDK 8u252+ project, and Shenandoah-enabled
downstream distributions should be released at the same time with 8u252 release, in mid-April.

Since we do not expect more non-critical backports until that release happens, what we have in
Shenandoah 8u tree is now the Release Candidate. Please test! Next 1..3 weeks are the perfect time
to identify problems with it and put in critical fixes that would land in April release.

As usual, you can try it by:
 a) Building from source yourself: https://hg.openjdk.java.net/shenandoah/jdk8/
 b) Taking our nightly builds: https://builds.shipilev.net/openjdk-shenandoah-jdk8/
 c) Using the Docker containers with nightly builds: shipilev/openjdk-shenandoah:8

Enjoy!
