There we go again. ;-) I can understand the wishes and cravings of the

there
should be another user survey to gather current data. Just because Sun
EOLs a Java version doesn't mean that everyone can suddenly just do
the
switch. So why don't those who want this change so badly do that
little
survey so we have the data on an informed decision?
As for retroweaving: I've just set the necessary values in my
build-local.properties and tried to compile the latest FOP Trunk with
Java 1.5. The build failed in the retroweaver task:

So that seems to indicate that the retroweaver business is not as
simple
as it sounds. Furthermore, has anyone done any serious tests in a
non-trivial environment (for example an enterprise-level application
running in an app server)? Maybe one of the stake holders around here
that still need to support a Java 1.4 environment can do such a test
and
report back here?
Don't get me wrong: I don't want to block this but I want this done on
an informed basis and with a vote, not just because the developers
like
generics. That's reasonable, isn't it?
What makes you think that?
(Sorry - couldn't resist.)
