Upgrade Java

[HandOfGod94]

Currently it's written in Java 8.
Certain features, needs to evaluated first:

• new module system capabilities of java 9+. All the third party libs should have module support.
• Change the annotation to JSR-330 for dependency injections.
• Evaluate the size of heavy fat run time that will be created if we use jmod and jlink as packaging instead of jars.
• Update maven version
• Update travis build scripts
