Since Java 7, Oracle Java and OpenJDK are nearly identical [0]. There's little reason to use the former instead of the latter. Previous to 7 OpenJDK had a much worse performance than the Sun/Oracle JDK, but that hasn't been true for a while now. It remains that the JVM is incredibly mature and performant, and almost any library you could want has been implemented on it. It also remains a fruitful ground for new language development, although LLVM is an increasingly popular alternative.
