jdk-8u45 - to my surprise the app worked straight away with only
java-1.8.0-openjdk-headless installed! Can some kind Java guru point me
to a link or summarise (in plain English) how this stuff works and the
relationship between Oracle's JDK and OpenJDK?
Oracle's proprietary JDK is based on OpenJDK, plus some extra features
and secret sauce. Java releases take great care to ensure backawards
compatibility (although it isn't always perfect) so I'm not surprised
that your program worked.
