------------------------------------------
Summary: Update ConcurrentLinkedDeque in Ignite's master
repository to the latest JDK version
Key: IGNITE-8486
URL: https://issues.apache.org/jira/browse/IGNITE-8486
Project: Ignite
Issue Type: Improvement
Reporter: Stanislav Lukyanov
Assignee: Stanislav Lukyanov
Ignite still uses copies of several JSR 166 (j.u.concurrent) classes in it's
sources. Those copies are now outdated compared to the latest versions used in
JDK.
In particular, `ConcurrentLinkedDeque` has received a couple of correctness
fixes recently (https://bugs.openjdk.java.net/browse/JDK-8188900,
https://bugs.openjdk.java.net/browse/JDK-8189387). It would be good to have
them in Ignite as well to protect ourselves from possible issues.
The task is to update Ignite's `ConcurrentLinkedDeque8` to the latest version
of `ConcurrentLinkedDeque`, although keeping compatibility with earlier Java
version (e.g. JDK's version now uses Java 9's VarHandles which we can't use
yet).
