NPE after ClientAbortException

After querying jersey and aborting the request I get the expected BrokenPipe and ClientAbort exceptions. But after that, I get a NPE while the server is trying to close the connection.

**Setup:** Jersey 2.25.1 in Apache Tomcat 8.5.12, but older versions are also affected.

**Stacktrace:**

The problem occurs because the recyle() in Http11OutputBuffer is called (which sets socketWrapper to null) before the commit() is called.

The cause may also be a bug in Tomcat, but I'm not able not decide this.
#### Environment
Debian, Oracle Java 8u121, Tomcat 8.5.11 or 8.5.12
#### Affected Versions
[2.25.1]

Start at org.glassfish.jersey.server.ServerRuntime$Responder.writeResponse and MappableExceptionWrapperInterceptor.aroundWriteTo, then trace the async resume path shown in the stack trace. Reproduce the aborted Jersey request on Tomcat 8.5.12 and confirm that connection closing after ClientAbortException no longer produces the reported NPE.
