[jira] [Created] (GEODE-9477) Geode membership will have issues on java 16 and later

Darrel Schneider created GEODE-9477:
---------------------------------------

             Summary: Geode membership will have issues on java 16 and later
                 Key: GEODE-9477
                 URL: https://issues.apache.org/jira/browse/GEODE-9477
             Project: Geode
          Issue Type: Bug
          Components: membership
            Reporter: Darrel Schneider


Geode membership uses setAccessible in a number of places to access jgroups internals. 
This will not work on java 16 and later (see: https://softwaregarden.dev/en/posts/new-java/illegal-access-in-java-16).

A workaround for this bug is to start the jvm with --illegal-access=permit

The places that call setAccessible in membership are:
* org.apache.geode.distributed.internal.membership.gms.messenger.AddressManager#findPingDataMethod (the catch in this method will not catch the RuntimeException thrown by setAccessible)
* org.apache.geode.distributed.internal.membership.gms.messenger.JGroupsMessenger#setChannelReceiver
* org.apache.geode.distributed.internal.membership.gms.messenger.JGroupsMessenger#start
* org.apache.geode.distributed.internal.membership.gms.messenger.JGroupsMessenger#checkForIPv6
* org.apache.geode.distributed.internal.membership.gms.messenger.JGroupsMessenger#establishLocalAddress
