There seems to be a mismatch between java command line version output and the contents of the release file. There is a strong expectation that java -fullversion reports the same string as JAVA_FULL_VERSION. Likewise with java -version and JAVA_VERSION. If there is a good reason for these to be different, please find better names for them.

 $ grep VERSION ~/jdk/jdk9/release; echo ---; ~/jdk/jdk9/bin/java -version; echo ---; ~/jdk/jdk9/bin/java -fullversion;
JAVA_FULL_VERSION="9-ea"
JAVA_VERSION="9"
---
java version "9-ea"
Java(TM) SE Runtime Environment (build 9-ea+167)
Java HotSpot(TM) 64-Bit Server VM (build 9-ea+167, mixed mode)

java full version "9-ea+167"
