• Update the packaged version of the Tomcat Native Library to 1.2.21 to pick up the memory leak fixes when using NIO/NIO2 with OpenSSL.

Warning: There is a known regression in catalina.sh script. In configurations that use a PID file (configured via CATALINA_PID environment variable) a wrong PID value may be written, or the file is not created at all. See bug 63041 (and 53930). The workaround is to use catalina.sh file from Tomcat 9.0.13.
