I apologize for not answering your immediate question (I think it might be quite difficult to predict what dirty legal tricks someone "might" pull in some uncertain future), but is your project really all that dependent specifically on OpenJDK? Or (if not) are you concerned that there might be some event in the future that will make running your code on any JVM (OpenJDK, IBM JVM, Oracle JVM, etc) impossible?
