Sorry of post to user list... now it is in dev list....
Besides, I will think that using pre-processor to build and maintain
multiple jdk version suppost is tedious... how about abstract all
variation to a custom util/io package ( I guess probably only IO and
collection, may be more but probably doable? ) And then when we build
and deploy, we using difference util/io package for target java
version, how do you think about it?
