> 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 Those copies are now outdated compared to the latest versions used in JDK.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).
