It's also the jdbc interfaces that are quite counter-intuitive. I mean,
closing the connection sounds reasonable, since you need to close the
underlying socket. However, the need to close statements and resultsets
explicitly is less obvious. What system resources should be involved with
formatting incoming and outgoing messages? All of that should be
automatically transient and should not hang on to any resources ... If it
does anyway, it is probably related to little-known features, that are of
The memory management problems with jdbc are therefore -- as usual -- the
result of extensive over-engineering along with unbounded feature growth; in
other words, it boils down again to the number one source of bugs in any
piece of software.
