I wonder how the $$ Google might pay to Oracle compares to the $$ it is spending to move away from Java by building replacements (v8, Go, Dart, Flutter/Fuschia, etc.) that are all essentially "GC languages with a great runtime VM". E.g. I can understand Oracle/Sun needing some amount of money for stewarding Java, as the teams required to build/maintain/QA/release the JVM were AFAIU in the hundreds, so not cheap. But…
V8 has little to do with Oracle, fundamentally. V8 came about because they wanted a higher performance JS VM for their browser; the JVM was never in contention there.
All of these JavaScript implementations use the V8 JVM and can make desktop and command line application. Depending on security settings they can give partial to full system access to the underlying OS just like Java. If this ruling is upheld I would look for Oracle to float a trial balloon on newer JavaScript implementations and for stealing their Java's API's.
