When launching a Java application through the command line, the system uses the default JDK. It is possible for the version of the JRE to be different than the version of the JDK.
You can determine which version of the JDK is the default by typing java -version in a Terminal window. If the installed version is 7u6, you will see a string that includes the text 1.7.006. For example:% java -version java version '1.7.006-ea' Java(TM) SE Runtime Environment (build 1.7.006-ea-b13) Java HotSpot(TM) 64-Bit Server VM (build 23.2-b04, mixed mode) To run a different version of Java, either specify the full path, or use the javahome tool: /usr/libexec/javahome -v 1.7.006 -exec javac -version For more information, see the javahome(1) man page.
