AzulJDK and Android JDK would be better examples, as Oracle JDK is just an Oracle-blessed build of OpenJDK.
The difference from libc though is that there is no problem in distributing a program with your preferred JDK, and multiple Java programs can live on the same system while each using its own JDK and even communicate risk free with each other.
Also, different JDKs are significantly more similar in the API they offer to Java programs than different libc are - at least for a common core of functionality.
