> Fix shutting down IsolatedJmx
> ------------------------------
>
> Key: CASSANDRA-18583
> URL: https://issues.apache.org/jira/browse/CASSANDRA-18583
> Project: Cassandra
> Issue Type: Bug
> Components: Test/dtest/java
> Reporter: Stefan Miklosovic
> Assignee: Stefan Miklosovic
> Priority: Normal
> Fix For: 3.11.x, 4.0.x, 4.1.x, 5.x

> {code:java}
> public class MyTest extends TestBaseImpl

> @Test
> public void test() throws Throwable
> {
> try (Cluster cluster = Cluster.build(2).withConfig(c ->
> c.with(Feature.values())).start())
> {
> ClusterUtils.stopUnchecked(cluster.get(2));
>
> System.out.println(cluster.get(1).nodetoolResult("status").getStderr());
> }
> }
> } {code}
> This will fail on this:
> {code:java}
> java.net.BindException: Address already in use (Bind failed)
> at java.net.PlainSocketImpl.socketBind(Native Method)
> at
> java.net.AbstractPlainSocketImpl.bind(AbstractPlainSocketImpl.java:387)
> at java.net.ServerSocket.bind(ServerSocket.java:390)

> at
> javax.net.DefaultServerSocketFactory.createServerSocket(ServerSocketFactory.java:231)

> {code}
> The problem is that IsolatedJMX clears whole map of TCPTransports in
> clearMapField as part of the stopJmx method. This results in JMX internals
> thinking the socket is not there so it tries to create it but it fails to do
> so because it is technically still bound.
> The fix is consisting of cleaning just the bits belonging to that specific
> IsolatedJMX instance.
> The investigation of the issue done by myself, the actual fix by [~drohrer].
> Found while working on CASSANDRA-18572.
