SaslUtils generates an illegal reflective access with jdk 11 and does not work with jdk 17

Hi,

while using jgroups 4.x with SASL activated, we get this message with jdk 11:

{{
WARNING: Illegal reflective access by org.jgroups.auth.sasl.SaslUtils (file:/path/to/lib/jgroups-4.2.18.Final.jar) to constructor com.sun.security.sasl.ServerFactoryImpl()
WARNING: Please consider reporting this to the maintainers of org.jgroups.auth.sasl.SaslUtils
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release
}}
 

Despite this warning, it works properly.

Now, since jdk 17 forbids illegal reflective access, jgroups 4.x failed with an IllegalArgumentException

No SASL server factory for mech DIGEST-MD5

I see that SASL have been removed in jgroups 5.x (JGRP-2377). Yet jgroups 4.x is used with a lot of other projects such as infinispan that claim to be jdk 17 compatible.

So I was wondering if there's any plan to make jgroups 4.x jdk 17 compatible ?

This documentation explains how to instantiate a SASL server.
