Where is Oracle's (Sun's) JDK/JRE installed on Mac OS X 10.8 Mountain Lion?

Question

Where does Oracle (Sun) install their JDK/JRE on Mac OS X 10.8 Mountain Lion?

Answer 1

On my system, evaluating which java leads me to /usr/bin/java. This in turn is a symlink to:

/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java

In case it's relevant, java -version tells me I have 1.6.0_37 installed.

Answer 2

The version 8 release from Oracle (1.8.0_40-b25) can be found at:

/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home/bin/java

FYI: Oracle is not following the practice of making /Library/Java/Current (etc) a link to the latest installed java.

Below is my method of keeping up with versions over time: from my .zshrc file:

108 JAVA_6_HOME=/System/Library/Frameworks/JavaVM.framework/Home
109 JAVA_7_HOME=/Library/Java/Current
110 JAVA_8_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_40.jdk/Contents/Home
111 
112 export JAVA_6_HOME
113 export JAVA_7_HOME
114 export JAVA_8_HOME
115 
116 export JAVA_HOME=$JAVA_8_HOME
117 
118 PATH=$PATH:$JAVA_HOME/bin
119
