Possible that abcl-2.0.0 will not support openjdk8
A question for all Bear fans: would you be severly impacted if abcl-2.0.0 dropped support for openjdk8, just supporting openjdk11 and up? In order to realistically get ABCL to implement Compare and Swap at all efficiently, I think we need to require that the JVM memory access model conforms to the fixes identified by Doug Lea et. al. as codified in the [VarHandle interface first introduced in openjdk9][varhandle]. abcl-1.8.0 would be the last release supporting openjdk8. Comments with this policy? Please yell early if you absolutely could not migrate an existing use of ABCL to openjdk11. [cas]: https://github.com/armedbear/abcl/issues/92 [varhandle]: https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/lang/invok... -- "A screaming comes across the sky. It has happened before but there is nothing to compare to it now."
I use ABCL on Java 8 in https://arahant.com/ and https://kissweb.org/ On Tue, Oct 6, 2020 at 10:57 AM Mark Evenson <evenson@panix.com> wrote:
