Within security bug 329937 there was discussion about stabilization of tomcat 5.5.32. Please consider completing that stabilization request. Thanks!
tomcat 5.5.x has been removed from the main tree because it's heading its eol in 2012-09-30 and it's unmaintained on our side (all the effort goes to 6.x and 7.x releases). tomcat 5.5.x has been moved to java-overlay for those that still need it.
