I was getting a NullPointerError somewhere inside mm.mysql, and didn't have a full stack trace. So I thought I would compile it in my tree, and take the opportunity to upgrade to 2.0.12. So I downloaded, unzipped and installed the source in my source tree. But the source does not compile - see errors below. Am I missing something? Sun J2SDK1.4.0 on Win2K. Jikes 1.14 gives even more errors (75 for one file).

(BTW, the I didn't need to recompile because 2.0.12 gave a proper error which told me what I was doing wrong - ResultSet.absolute (0)).
