[ANN] Apache Tomcat 8.5.75 available

[Christopher Schultz <sc...@apache.org>]

The Apache Tomcat team announces the immediate availability of Apache
Tomcat 8.5.75.

Apache Tomcat 8 is an open source software implementation of the Java
Servlet, JavaServer Pages, Java Unified Expression Language, Java
WebSocket and Java Authentication Service Provider Interface for
Containers technologies.

Apache Tomcat 8.5.75 is a bugfix and feature release. (Note that Tomcat 
8.5.74 was not released.) The notable changes compared to 8.5.73 include:

- JmxRemoteLifecycleListener has been removed.

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

- Fix several potential JVM crashes when using the APR connector.

- 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.

- Implement support for HTTP/1.1 upgrade when the request includes a
    body. The maximum permitted size of the body is controlled by
    maxSavePostSize.

- Improve handling of various cases where one request/response
    processing thread attempts to manage the asynchronous IO for a
    different request/response.

Along with lots of other bug fixes and improvements.
