For the specific beans he asked about, I'm pretty sure you need to swap
the connector jars.  The jsr77Names attribute is not documented (and set
to false by default) so one would have to look at the code to know of it
;)  Given those two, you can't get that data with 4.1.30 out of the box,
which is why I said no, and I don't think that's FUD ;)
