What lightweight OSGI alternatives do you know of?

Question

Java

Good time of the day!
I develop client-side software for java 1.8. I would like to find a lightweight, simple library with the ability to dynamically load bundles (*.jar), call objects from them. Similar to OSGI. In this case, you need to save time, so the bike is the last option.
What solutions in this area do you know?

UPD aol-nnov : Right, missed the word "alternatives" - and answered the wrong question. Haven't heard of alternatives.

To build your jar as a bundle, you can use the maven-bundle-plugin . By default, it sets up the manifest for the bundle quite well.
