Not that I'm aware of, since SQLException doesn't extend IOException.  That 
said, it might be nice to have a java.sql.Closeable for some future JDBC...

I guess once you have that, you could do a java.lang.Closeable with a close 
method that throws Exception, and derive both java.io.Closeable and 
java.sql.Closeable from that. :-)

Though I'm not 100% certain what impact inserting an interface above 
java.io.Closeable in the heirarchy would have on backwards compatibility.
