Java 8 incompatible

[sannysoft]

Hello. Thanks for a great lib.
Unfortunately lib doesn't seem to be working with Java 8:
- Incompatible because this component declares a component compatible with Java 11 and the consumer needed a component compatible with Java 8

Hmm, yeah I probably built it with JDK 11. Will add toolchain logic into the build so that the next version is built on JDK 8.
