Tomcat: install APR

$ sudo apt-get install libtcnative-1

Verify installation: when Tomcat start in catalina.sh should exist the line "INFO: Loaded APR based Apache Tomcat Native library 1.1.19."

But for Tomcat v.7.0.23 (still not solved): "INFO: An older version 1.1.19 of the APR based Apache Tomcat Native library is installed, while Tomcat recommends a minimum version of 1.1.22"

Comment: what's the difference with the package libapr1?
