jCoreExtras

Written by Martin Pearman

jCoreExtras wraps native java classes into B4J objects.
It wraps classes that are not (yet) part of the official B4J jCore.jar library.
My plan is to keep all newly wrapped native java objects in this single library,
this library can then be referenced by other libraries that require the wrapped java objects.
jCoreExtras can be found on GitHub at: https://github.com/warwound/jCoreExtras
You're welcome to contribute!
