          Components: Broker

A ConcurrentModificationException is raised;

Configuration:

Artemis (2.16.0) is deployed in Wildfly (24.0.1.Final)

Clients are connected to stomp acceptor:

<acceptor name="stomp-over-ws" factory-class="org.apache.activemq.artemis.core.remoting.impl.netty.NettyAcceptorFactory">
<param name="host" value="0.0.0.0" />
 <param name="protocols" value="STOMP" />
 <param name="port" value="61614" />
 </acceptor>

 

Bug is random but is reproduced quite often with a full scenario we have (on one topic or another) so we are able to reproduce it and add logs if necessary.
