Bug 1363: Java 11: Initial Host/Target Compiler Selection: Java8

Current requirements are:
  - Java 1.8 (Level 8.0)
  - Android SDK API level 24 (Version 7.0 Nougat, released August 2016)

Official production builds are performed w/ Java 1.8.
  - Java 1.8 (Level 8.0)
  - Android SDK API level 24 (Version 7.0 Nougat, released August 2016)

  Android 7 API level 24 supports Java 1.8,
  see https://developer.android.com/studio/write/java8-support

  Java 8 is chosen today, June 2019, since OpenJDK 1.8 is well supported
  on desktop, mobile support is given w/ OpenJDK 9 and
  Android also support these language features for almost 3 years.

++++

Current patch does require one to set the target.sourcelevel,
target.targetlevel and target.rt.jar properties or their equivalent
capital case environment variables.

Only allowed value is currently 1.8.

-     Android supports Java language level 6.0.
-     Nevertheless, it cannot be guaranteed whether the Android API
-     supports all classes and methods of Java 1.6.
-     It is required for JogAmp developers to validate Android compatibility
-     by an Android crosscompilation build.
-
-     Current GlueGen code utilizes some minor Java 1.6 features
-     which could be replaced, however it's not desired at this point
-     since we have no mode hard Java 1.5 constraints.
