Java 6 / 1.6 OS X 10.10 Yosemite的JVM路径在哪里？

Question

I can find the latest update for Java 1.8 at

ls /Library/Java/JavaVirtualMachines/

which only lists

jdk1.8.0_05.jdk

and not the Java 1.6 that I installed following updating to Yosemite?

I need Java 6 for a legacy product that I'm maintaining, and the eclipse IDE

Answer 1

Since's it's the last version of Java that built and maintained by Apple it's on a different path, under /System and not /Library :

>ls -l /System/Library/Frameworks/JavaVM.framework/Versions/

Gives:

1.4     1.4.2       1.5     1.5.0       1.6     1.6.0
A       Current     CurrentJDK

Running this command /usr/libexec/java_home -V shows the locations of the various installed Java versions, sample output:

Matching Java Virtual Machines (3):
    1.8.0_25, x86_64:   "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home
    1.6.0_65-b14-466.1, x86_64: "Java SE 6" /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
