jdk8 feature in jdk7

[Romain Gilles]

Hi all,
I'm really interesting in the jdk8 java.util.function package and to be
more precise the java.util.function.Supplier<T> class.
I would like to create a jar file that contains only those (or maybe this)
class(es). To avoid to use guava instead and allow a smooth migration to
the jdk8 as soon as it is available.

The other constraint is: can I publish it in maven repository (centrale /
sonatype) with the respect of any licenses?

Thanks in advance,

Romain
