Major Description
I was looking up a class using the javadocs search functionality, and clicked on the link when TaskId came up, but it sent me to which https://kafka.apache.org/28/javadoc/undefined/org/apache/kafka/streams/processor/TaskId.html does not exist.
I noticed the URL had an odd "undefined" term inserted before the package name, so I took that out and was able to find the correct javadocs. So the search seems to be broken due to this "undefined" term that's being injected somewhere, for some reason.
