-------------------------------------

             Summary: IntrospectionSupport should call method.setAccessible(true)
                 Key: AMQ-7121
                 URL: https://issues.apache.org/jira/browse/AMQ-7121
             Project: ActiveMQ
          Issue Type: Bug
    Affects Versions: 5.15.8
            Reporter: Ollie Robertshaw


We are trying to run a broker in JDK 11 and run into the following exception:
{code:java}
2018-12-07 12:44:41,363 ERROR main o.a.a.u.IntrospectionSupport Could not set property soTimeout on ServerSocket[addr=/0:0:0:0:0:0:0:0,localport=9505]
java.lang.IllegalAccessException: class org.apache.activemq.util.IntrospectionSupport cannot access a member of class sun.nio.ch.ServerSocketAdaptor (in module java.base) with modifiers "public"

This is caused by {{sun.nio.ch.ServerSocketAdaptor}} becoming a non-public class in JDK 11 (if not earlier).

It can be fixed simply by having {{IntrospectionSupport.setProperty}} call {{setter.setAccessible(true)}} before it invokes any methods on it.
