Reimplement logic to find Java version in JavaVersion.java

[Mesbah-Alam]

We should remove the version check altogether and update the logic of figuring out various Java versions in JavaVersion.java to depend on Java system properties instead of parsing java -version output.

Hi! Trying on work on this task but I could not find any tests to verify the changes are correct. Any suggestions on how I should test my changes or should I open a PR directly for review?
