/**
* Implementation of <code>LifecycleListener</code> that will init and
* and destroy APR.
+ * <p>
+ * <strong>Note</strong>: This listener must only be used within a {@code
Server}
+ * element to manage APR/OpenSSL init and destroy JVM-wide. If you are running
+ * Tomcat in an embedded fashion and have more than one Tomcat instance per
JVM,
+ * this listener <em>must not</em> be added to the {@code Server} instance, but
Review comment:
Maybe this is too subtle for Tomcat's javadoc, but this isn't strictly
true. You can safely add the listener to a `Server` (or even a `Context` if you
know there will only be one) as long as that `Server` is started first and
stopped last. In the absence of an API that's designed to manage the lifecycle
of APR outside of Tomcat's `Lifecycle` and `LifecycleEvent`, I suspect that's
what we'll do in Spring Boot if the Tomcat team decides not to make
`AprLifecycleListener` more robust.
