Enabling the Checker Framework to handle JDK 9

This project is about enabling the checker framework to handle JDK9. As of now, the checker framework runs only on JDK 8. Since JDK 9 has already been released and JDK 10 is around the corner, the checker framework needs to be handling them. Many project owners are not able to use the power of such a powerful framework owing to the compatibility issues. This project attempts to make the checker framework compatible with JDK 9. Moreover, it also attempts to create a log file of the changes made to the framework, which can then be implemented as an instruction set for the people who want to annotate the JDK or make the framework compatible with the future releases of Java.
