Description

When ActiveMQ running ActiveMQ on Java 17 or later JRE, it encounters following exception:

ERROR | Could not set property soTimeout on ServerSocket[addr=/0:0:0:0:0:0:0:0,localport=xxxxx] | org.apache.activemq.util.IntrospectionSupport | main
java.lang.reflect.InaccessibleObjectException: Unable to make public void sun.nio.ch.ServerSocketAdaptor.setSoTimeout(int) throws java.net.SocketException accessible: module java.base does not "opens sun.nio.ch" to unnamed module @4739cd70

According to Oracle, with JEP 403 (link1) and JEP 403 (link2) which has been decided to be delivered from JDK 17 and onwards , the setAccessible approach which was introduced as part of https://issues.apache.org/jira/browse/AMQ-7121 wont work.

 

Fix:  Adding the following in activemq file should do the job:

--add-opens java.base/sun.nio.ch=ALL-UNNAMED
