John, are you specifically after a 'graph database', or a 'pure java' database?
H2 is an example of a pure java database, which is >99% zIIP eligible, in my experience. Any pure java library (typically in the form of jar file[s]) should 'just work' on z/OS (i.e. no porting required). Havent quite worked out though, if Neo4j is actually a java library, or something that is "binaried" to specific platforms. There seems to be a jar file available, but is not clear if that is the actual product, or just some 'helpers' to interface with java. Neo4j advertises being capable of generating actual graphs from DOT directed graph notation, and if that is do-able from a pure java capability, that is something I have been patiently waiting for for many many years.....so will be investigating that further, for sure.
