Theres no stable released project that uses a jdk1.5-like 
model for attributes (and only one semi-developed one). And 
there is no direct compatibility that I am aware of (though 
this may have changed in the last few months).

It would be a lot of work to adapt a toolkit that reads and 
writes jdk1.5 attributes but I am not sure it will happen. 
jdk1.5 is just too close.
