Answer 1

Had the same issue when I installed Java 9. My project would default to J2SE-1.5 Execution Environment. Strangely, Java 9 compliance level is not referenced like previous versions, i.e. "1.8", but as "9". So I had to provide my properties and Maven compiler plugin config accordingly:

    9
    9

and

    org.apache.maven.plugins
    maven-compiler-plugin
    
        9
        9
    

This seems to have solved the problem. Works for versions 9 and above.
