• When I look at System Preferences > Java > Update, I see

    Your system has the recommended version of Java.
    Java 7 Update 79

  • From Terminal, java -version:

    java version "1.7.0_71"
    Java(TM) SE Runtime Environment (build 1.7.0_71-b14)
    Java HotSpot(TM) 64-Bit Server VM (build 24.71-b01, mixed mode)

  • From Terminal, export:


  • In addition to that, I also have the Java from Apple/Oracle installed as well (when first prompted to install when opening a Java-based app when there's no Java yet installed)


  1. Is Java 7 Update 79 == jdk1.7.0._71.jdk? Or are these separate?
  2. When running some thing with Java, there is always the following:

    objc[63077]: Class JavaLaunchHelper is implemented in both /Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home/jre/bin/java and /Library/Java/JavaVirtualMachines/jdk1.7.0_71.jdk/Contents/Home/jre/lib/libinstrument.dylib. One of the two will be used. Which one is undefined.

I'd be more than willing starting from scratch had I understood the steps to do that properly (remove, re-install). If it matters, am running OS X 10.10.


System Preferences shows the Java used for web applets and java -version the one found by /usr/bin/java

To get the latter install the JDK not the JRE

  • Okay. Downloading "Java SE Development Kit 7u79" for OS X. – Idan Adar May 23 '15 at 8:12
  • After installing it, "java -version" still shows _71. I suppose that is because of the JAVA_HOME path? – Idan Adar May 23 '15 at 8:14
  • We need to get more accurate on the correct download path Oracle has really messed this yp – mmmmmm May 23 '15 at 8:16
  • After updating JAVA_HOME, "java -version" now showing _79, so that's up-to-date now. However the error mentioned in question #2 remains. – Idan Adar May 23 '15 at 8:16
