问题
We are testing neo4j 2.2.2 with java 8u45 but we are seeing an error when we start neo4j.
ERROR! Neo4j cannot be started using java version 1.8.0_45.
* Please use Oracle(R) Java(TM) 7 to run Neo4j Server. Download "Java Platform (JDK) 7" from:
http://www.oracle.com/technetwork/java/javase/downloads/index.html
* Please see http://docs.neo4j.org/ for Neo4j Server installation instructions.
Still the database starts, so the question is: Is this Error message a bug or we should revert the java 8 version to 7.
Error is trigger on /bin/utils script on function checkjvmcompatibility()
Thank you !!!
回答1:
It clearly says that you should use Java 7. This is a system requirement, enforced by the library.
But the release notes on the http://docs.neo4j.org/ say:
Neo4j 2.2.2 is a maintenance release, with critical improvements. Notably, this release: Provides full support for Oracle and OpenJDK Java 8.
So either there's a mistake in the documentation, or (more likely) they forgot to update the compatibility check utility. Send them a message on this problem.

According with the neo4j team: it is a bug that will be fixed in an upcoming maintenance release (thank you Viksit Puri).
So release notes are fine and java 8 works well with neo4j version 2.2.2 of Neo4j
