I'll appreciate links to previous discussions about the subject but let's say I create the next big thing in the JVM world(the next Kotlin compiler or something like that), it targets the JVM and I happen to replace the implementation of `String.getBytes` at linking time while keeping the same method signature. How big do I have to be for Oracle come after me and ask for royalties of any Enterprise services I could be selling on top of my product?
