@ChristopherSchultz Here is an extremely primitive test case:
```java
public class TomcatEmbeddedTest {
static class ShutdownHook2 extends Thread {
Tomcat tomcat;
Tomcat tomcat2;
public void run() {
try {
Thread.sleep(5000L);
} catch (InterruptedException e1) {
e1.printStackTrace();
}
try {
tomcat2.stop();
tomcat2.destroy();
tomcat.stop();
tomcat.destroy();
} catch (LifecycleException e) {
e.printStackTrace();
}
}
}
public static void main(String[] args) throws LifecycleException {
Tomcat tomcat = new Tomcat();
tomcat.setPort(18888);
AprLifecycleListener listener = new AprLifecycleListener();
listener.setUseAprConnector(true);
listener.setUseOpenSSL(true);
tomcat.getServer().addLifecycleListener(listener);
tomcat.getConnector();
tomcat.init();
Tomcat tomcat2 = new Tomcat();
tomcat2.setPort(28888);
AprLifecycleListener listener2 = new AprLifecycleListener();
listener2.setUseAprConnector(true);
listener2.setUseOpenSSL(true);
tomcat2.getServer().addLifecycleListener(listener2);
tomcat2.getConnector();
tomcat2.init();
ShutdownHook2 sh2 = new ShutdownHook2();
sh2.tomcat = tomcat;
sh2.tomcat2 = tomcat2;
sh2.start();
tomcat.start();
tomcat2.start();
}
}
```
Output:
```
