I don't think the JVM is in any particular danger of disappearing, otherwise I wouldn't be still programming in it :)
However, a technology controlled by a single vendor, even one as large as Oracle, is at greater risk than one that is an open standard with several competing implementations. I'd be happier if Oracle were encouraging alternative JVMs, rather than suing them or withholding testkit licenses.
