<!-- Current runtime 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 _for_ Java 1.8.
        - Java 1.8 (Level 8.0)
        - Android SDK API level 24 (Version 7.0 Nougat, released August 2016)

     Official production builds are performed _on_ OpenJDK 11
     and a Java JDK 11 or greater is required!

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

     Target Java 8 baseline 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.
     
     For crosscompilation the following shall be set:
     - TARGET_PLATFORM_SYSROOT Crosscompiler and system specified 'sysroot' (as in gcc \-\-print-sysroot)
     - TARGET_PLATFORM_USRROOT Additional optional user headers and libraries for target
     - TARGET_PLATFORM_USRLIBS Actual location of target user libraries within TARGET_PLATFORM_USRROOT
     - TARGET_JAVA_LIBS Actual location of the Java libraries within TARGET_PLATFORM_USRROOT
