This is the Changelog for Tomcat 5.5.x, which was branched based on Tomcat 5.0.27. For changes in Tomcat version 5.0.x, which preceded version 5.5.0, please see The Tomcat 5.0.x Changelog. As maintenance releases are cut on the 5.0.x branch, most fixes will be ported into a 5.5.x release and noted both here and in the above Changelog. However, bugs fixed in Tomcat 5.0.28 and earlier are noted only in the above changelog.

fix Give proper permission to the balancer app when running under the security manager. (jfarcand)
fix 30869: Make sure JAAS realm name is legal. (yoavs)

docs Update the connector documentation. (remm)

fix Digester handling fixes: always call reset in a finally block after using a digester. (remm)
update Remove many fields from Connector, and tie the creation of the Connector to the creation of the protocol handler. (remm)
update Remove package triggers from the classloader, which seem useless when using Java 5. (remm)

fix Fix issue with getProperty in IntrospectionUtils. (remm)
update Remove attribute translation for SSL in the HTTP protocol handler: it will now be done in the Catalina Connector class. (remm)
fix Fix handling of the "timeout" attribute of the HTTP protocol handler. (remm)
fix 31171: Wrap to avoid ClassCastException in PageContextImpl. (yoavs)
fix 31257: Added specification of endorsed dirs if forking. Note that this is fairly useless for now in 5.5 since it uses JDT and not javac by default. (yoavs)
docs Document new Jasper defaults, and update the production configuration. (remm)
fix Copied XML encoding detection logic into JASPER, so we're no longer dependent on Xerces. (luehe)
fix Fix cosmetic issue where extra CRLF would be inserted during each precompilation in web.xml. (remm)

Tomcat 5.5.0 (yoavs)
update Many updated and fixed JavaDocs. (yoavs)
update Designed and tested Tomcat on J2SE 5.0 (aka JDK 1.5). (everyone)
update Bundled Eclipse JDT (new dependency) to allow Tomcat to run on a JRE only, i.e. no JDK required. (remm)
update Repackage commons-dbcp and its dependencies as a sigle smaller WAR, with renamed packages. (remm)
update Removed dependencies on commons-digester, commons-beanutils, and commons-collections. The relevant digester functionality is now merged in tomcat-util. (remm)
update Removed usage of org.apache.catalina.Logger, increased usage of commons-logging everywhere. (remm)
update Refactored classloader code to better handle JAR and general resource locking. (remm)
update Written JMX-related code to play nicely with J2SE 5.0 built-in JMX abilities. (remm, costin)
update Extensively profiled and optimized the server startup performance as well as the request mapping and processing pipeline. (remm)
update The container will now always process a /META-INF/context.xml resource, unless the webapp has a specified external context file. (remm)
update New default configuration mechanism for web applications, replacing DefaultContext. This uses a shared context file located in conf/context.xml. (remm)
update Revamped deployer, alloying full hotdeploy (note: on Windows, this requires the anti file locking features). (remm)
update Remove verbosity from the JNDI resources configuration, by allowing arbitrary attributes on the Resource element. (remm)
update Simpler Valve interface, to allow smaller stack traces and reducing the amount of method calls. (remm)
update Eclipse JDT is now the default Java compiler in Jasper. Source dependencies are now loaded from the container classloader, and compilation times are much faster. (remm)
update Jasper development mode should now have acceptable performance for heavily accessed pages. Precompiling JSPs is still significantly more efficient, however. (remm)
