I use JLS extensively both as a learning and teaching resource, but I've noticed that there are some errors in it.
There's the simple typos (e.g. JLS 5.1.4 "convesions"), but there's also some that I consider quite serious errors.
For example, JLS 18.1 The Grammar of the Java Programming Language is supposed to be the authoritative reference for the grammar of the Java language, but it contains a production rule that never gets used! (e.g. MoreStatementExpressions). Surely this is a sign of more serious errors in other parts of the given grammar, right?
So is there an errata for the 3rd edition? Will there ever be? Should we send errors we've found to Sun/Oracle? Will there ever be a 4th edition?
