Those seem to be general JAVA questions, addressed by the JAVA specification, rather than OpenJDK/Zulu specific. In short:
JAVA

  • 64bit memory limit is in the terabyte range
  • The JDK containes both the compiler (javac) and the runtime (java)
  • Arithmetic: Please check the Java specification. Zulu complies with 100% with the Java specification.
  • No JavaME – sorry, this is dying
    • Android has its own versio of JAVA. No need to install another JVM
    • Apple does not allow unrestricted JAVA on iOS. The ones available make interesting compromises to run.
    • Microsoft Smartphone – Whats that? Never heard of Microsoft selling Smartphones. Who would want a smartphone he has to reboot twice a day?
