They're missing from both http://jakarta.apache.org/tomcat/tomcat-5.5-doc/catalina/docs/api/index.html). and the fulldocs.tar.gz bundle. Check/fix the "dist" target of build.xml
It's because the relevant part of the dist-javadoc target in jakarta-tomcat-5/build.xml is commented out.
A bit more complicated: the build/release scripts are fine. JSSE15SocketFactory.java has 2 fatal JavaDoc errors when generating the JavaDoc on JDK 1.4, which is what we do when releasing Tomcat.
OK. I've generated the docs and put them on the live site. I've updated build.xml so this won't happen again for Tomcat 5.5.11 and beyond.
