Hi everyone ! The following JBoss CLI command : /subsystem=ejb3:write-attribute(name="default-mdb-instance-pool", value="mdb-strict-max-pool") is not working anymore with WildFly 21.0.0.Final and gets an error : WFLYCTL0158: Operation handler failed: java.lang.IllegalStateException: WFLYCTL0365: Capability 'org.wildfly.ejb3.pool-config.mdb-default' is unknown in context 'global'. We used the CLI command since WF17 with no problem. Is there anything changed in WF21 (WFLY-13433 ?) that can explain the error ? Is the command useless or do we need to run another command before ? Thank you ! David Le Borgne
