问题
I'm having issues starting my neo4j instance (2.0.0 M03). I have java 7 installed as indicated in the code block below but when trying to start neo4j it apparently does not recognize this, gives and error and does not start. The terminal output is below. Any ideas on how to fix this or what exactly is going wrong? Thanks a lot.

The problem was JAVA_HOME was not set to the correct JVM. To determine where you have your instance installed you can enter the following into terminal:
/usr/libexec/java_home -v 1.7
This should return the location, in my case: /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/
To set JAVA_HOME just export pointing towards the location like below (enter into the console):
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home/
