[jdom-interest] Java 1.5 language features.

Or you release a new version with generics and introduce maintenance
builds for the 1.4 supporting version when and if bugs need to be
fixed. You can't wait for an entire user.base to move on - there are
still people using 1.1.x after all.
NB: @SuppressWarnings really should be the exception rather than the
rule (EG filling in those edge cases where Suns partial generics
implementation shows its gaps). I wouldn't want to have to pepper the
code with suppression for every touch point where we use JDOM.
