Dear All,

What is the difference between HashMap in alt-rt.jar
and rt.jar. I think I see a considerable speed up
in one of my applications, what would be the explanation?

Bye

I've never even heard of alt-rt.jar. What is that?

in the OpenJDK repositories somewhere, but they're a nightmare to
navigate.
