This months OCI internal Java lunch is an introduction to ANTLR 3 and AntlrWorks by Dean Wette. I didn't take good notes, so I can't do a live blog today.

Like what I did 7 days ago with the St. Louis JUG meeting, I'm going to turn the talk into a Java Quiz. (Dean did ask me "No Friday Java Quiz today?" to which I replied "No.")

Well, Friday is not over yet. And Dean may be surprised to find this quiz when he gets back to the client site. I do have a parser generator related question for you. To set it up, let me just mention that if you write a parser in Antlr 3, you will have to ship the Antlr 3 runtime with your final product. This is not the case for JavaCC.

Now the question: How many parser-generator runtimes does the Sun JDK (say Java 6) contain? What are they?
