Java is too entrenched as a language to seriously languish in 5 years. Its popularity for new projects might be significantly reduced, but there'll still be a ton of work available due to the built-up glut of projects and developers (even more so than COBOL ever experienced).
Java as an ecosystem and including the VM? We might see it splinter a little but the VM is even more entrenched than the language. There are too many other languages and ecosystems sitting on top of the JVM and its compatible libraries that I doubt any damage will be negligible in 5 years even if Oracle really screws things up from here.
