app bundles using Apple's JavaApplicationStub will use Apple Java 6 from /System/Library/Frameworks, and new-style ones built with AppBundler without a bundled JRE will use the 'public' JRE in /Library/Internet Plug-Ins/ugin/Contents/Home - that's hard-coded in the stub code and can't be changed, and you can't have two different public JREs installed at the same time.Įdit: I've had a look at VisualVM specifically, assuming you're using the 'application bundle' version from the download page, and this particular app is not an AppBundler application, instead its main executable is a shell script that calls a number of other shell scripts and reads various configuration files. export JAVA_HOME='`/usr/libexec/java_home -v '1.7*'`'īut standard double-clickable application bundles don't use JDKs installed under /Library/Java at all. The command-line tools like java and javac will respect that environment variable, you can use /usr/libexec/java_home -v '1.7*' to give you a suitable value to put into JAVA_HOME in order to make command line tools use Java 7.

I think JAVA_HOME is the best you can do. While this answer offers what amounts to a hack that will remove versions of Java from being picked up by java_home, it still does not answer this question of how java_home chooses its default and whether or not users can non-destructively set it. Re-naming the JDK 1.8 directory to jdk1.8.0.jvm.xyz does not change anything: java_home still finds it in the right place, and running /usr/bin/java still executes the 1.8 JVM. Oracle JVMs live in /Library/Java/JavaVirtualMachines. (Please don't tell me to launch the Java Preferences Panel because that simply does not work: it does not contain anything useful and only lists one of the 4 JVMs that I have installed.) So, is there a file I can edit where I can set my JVM ordering preferences globally? I can't set JAVA_HOME because launching applications ignores environment variables, even when launching from the command line (e.g. That means that the default version of Java is currently the pre-release version, which breaks some 'normal' packages (in my case, VisualVM).

I recently installed Oracle's 1.8 preview JDK for some pre-release software that requires it.

I am running Mac OS X 10.8.4, and I have Apple's JDK 1.6.0_51 installed as well as Oracle's JDK 1.7.0_25. migration is certainly an option, but more programmers read questions here, so here goes).
