yeah its a pain - even if we have to target 1.5 (which is entirely
reasonable for the next few releases) we can probably *require* that
it is built with JDK6, using whatever dirty tricks there are to make
the bytecode work with 1.5.
Apparently the EOL is for the Sun JVM, the IBM and other ones have a
longer life, it seems (and in many cases, the EOL of support on the
core JVM is ignored by users, more so then the app servers or
libraries or applications they run on top ! I have no idea why it is
that way, it just is. Probably like how some places still have Windows
2000 or NT around !).

That doesn't work, as the maven compiler plugin is already set to use
source 1.5 in the main pom and I can't compile with jdk 6. It can only
be compiled with jdk 5 it seems, not jdk 6.
With kind regards,
