enable JDK 11 builds

[vladak]

The major part of the change is passing --illegal-access=permit (and other options) to java for JDK 9+.

I had to bump the chronicle-map to the latest release otherwise suggester tests were failing in init().

💛 - Coveralls

Also, jacoco has to be upgraded: jacoco/jacoco#663

Another gotcha are JDK versions identified in the Maven profiles' <activation> elements - e.g. JDK 8 is 1.8, JDK 11 is 18.9.

Also, jacoco:report has to be present on the Maven command line before the coveralls goal is invoked, otherwise the build fails with strange errors in Coveralls plugin processing - it will find that Jacoco reports line counts higher than the current length of some files (I think it was happening in the JavaScript generated lexer).

Due to this, I was not able to convert Jacoco to a profile like I did in https://github.com/vladak/maven-surefire

Similarly, I wanted to make Coveralls to become Maven profile however this leads to AppVeyor failures since Coveralls does not have the auth token available there, unlike in Travis.
