Subject [FYI] Tomcat 4.0.4 beta1 - release notes
Date Tue, 05 Mar 2002 18:02:43 GMT
Interesting release notes that affect Tombat, from

Tomcat 4.0 and Apache Cocoon 2.0:

For optimal performance with Apache Cocoon 2.0, it is recommended to use the
HTTP/1.0 connector.

Tomcat 4.0 and XML Parsers:

As described above, Tomcat 4.0 makes an XML parser (and many other standard
APIs) available to web applications.  This parser is also used internally
to parse web.xml files and the server.xml configuration file.  If you wish,
you may replace the "xerces.jar" file in "common/lib" with another XML
as long as it is compatible with the JAXP/1.1 APIs.

JAVAC leaking memory:

The Java compiler leaks memory each time a class is compiled. Web
containing hundreds of JSP files may as a result trigger out of memory
once a significant number of pages have been accessed. The memory can only
freed by stopping Tomcat and then restarting it.

The JSP command line compiler (JSPC) can also be used to precompile the

Tomcat 4.0 and Sun JDK 1.4 beta 3:

Some unpredictable classloading behavior has been reported when Tomcat is
used with Sun JDK 1.4 beta 3. The problem has been fixed with Sun JDK 1.4
Realease Candidate or later.
