[compress] Which Java version to use?
Hi all,
I've just merged two changes made to the Ant zip code base -
commons-compress' great-grand-parent - into the sandbox and intend to
keep doing this as we make changes in Ant.
There is another change in Ant that may lead to a tiny performance
improvement by using JDK 1.4 collections (LinkedHashMap) instead of
Java 1.1 ones. I'm not sure whether I can savely merge this or
whether commons-compress intends to target JVMs < 1.4.
Is there some sort of official baseline?
Stefan

Yeah, I would think it safe to say we target 1.4+. I would even
consider going 1.5+. But it doesn't really help the API much IMO.

Hi
there is no official baseline, but we use some 1.4 features in
compress and we didn't feel the urgent need to optimize for 1.1. I
would say go for it.
Cheers
