Subject Tomcat slow during startup >= 7.0.28
Date Mon, 14 Jan 2013 14:11:58 GMT
Hi!
I've noticed, that Tomcat got much slower during startup. When using a Version > 7.0.27
(+ Oracle JDK 7), it takes much longer.

Jan 14, 2013 2:12:40 PM org.apache.catalina.core.AprLifecycleListener init
INFO: Loaded APR based Apache Tomcat Native library 1.1.24 using APR version 1.4.6.

INFO: Starting service Catalina
Jan 14, 2013 2:12:40 PM org.apache.catalina.core.StandardEngine startInternal
INFO: Starting Servlet Engine: Apache Tomcat/7.0.32

After this Step, with a newer version, it can take several minutes, until it continues.
During this "pause", I can see, that the disk i/o is pretty high. 
When I switch back to an older version < 7.0.27, this goes much faster. It just takes seconds.

I am using a stock default config, only added "URIEncoding="UTF-8"". Tested with Windows 7
Professional and Ubuntu 12.04. 

I don't know where to start for debugging this problem. Any Ideas?
