dropped support for openjdk8, just supporting openjdk11 and up?<br>
<br>
In order to realistically get ABCL to implement Compare and Swap at all<br>
efficiently, I think we need to require that the JVM memory access model<br>
conforms to the fixes identified by Doug Lea et. al. as codified in the<br>
[VarHandle interface first introduced in openjdk9][varhandle].<br>
<br>
abcl-1.8.0 would be the last release supporting openjdk8. Comments with this<br>
policy? Please yell early if you absolutely could not migrate an existing use<br>
of ABCL to openjdk11.<br>
