@OGKevin

I've already started working on this, feel free to finish it however. You can do this by creating your own branch as child of my branch which is https://github.com/bunq/sdk_java/compare/add_java_7_support_bunq/sdk_java%2342 and then create a PR that merges into my branch. Afterwards this gets merged in develop.
