That's true - but it wasn't until recently that the lo examples had
BEGIN and END in them.
It's on my list to get the JDBC examples to setAutoCommit(false).
Hopefully I'll get some time today to do this.

Hmm. The documentation does say somewhere that LO object handles are
only good within a transaction ... so it's amazing this worked reliably
under 6.4.x.
Is there any way we could improve the backend's LO functions to defend
against this sort of misuse, rather than blindly accepting a stale
filehandle?
