Given the volume of Java code in production and the fact that lots of shops still use Java as their primary development language, there will be employment opportunities in Java into the indefinite future both supporting existing systems and creating new.
Given that Java is a reliable, general-purpose language with a vast native library and multiple frameworks, it offers fully as much potential value as any other such language.
Given that Java promotes OOP, to the degree that OOP remains popular, Java should ride its coattails.
Personally, I'm a fan. I don't have to use it for everything and don't, but, when I DO use it, I know the results are solid.
