[ANN] Apache Tomcat 9.0.56 available

[Rémy Maucherat <re...@apache.org>]

The Apache Tomcat team announces the immediate availability of Apache
Tomcat 9.0.56.

Apache Tomcat 9 is an open source software implementation of the Java
Servlet, JavaServer Pages, Java Unified Expression Language, Java
WebSocket and JASPIC technologies.

Apache Tomcat 9.0.56 is a bugfix and feature release. The notable
changes compared to 9.0.55 include:

- Provide protection against a known OS bug that causes the acceptor to
   report an incoming connection more than once.

- Implement a workaround for a JVM bug that can trigger a file
   descriptor leak when using multi-part upload and the application does
   not explicitly close an input stream for an uploaded file that was
   cached on disk.

- Fix exceptions when the security manager is enabled and the first
   request received after starting is an HTTP request to a TLS enabled
   NIO2 connector.

Along with lots of other bug fixes and improvements.
