Where did jvisualvm go?

I am running Mac OSX Snow Leopard.

I've always updated Java using the regular Software Update features of Mac OSX.

I've used the Java jvisualvm tool in the past with great success.

This morning I typed jvisualvm into the command line as I often do. I got the following error:

 $ jvisualvm
 Unable to locate an executable at "/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin/jvisualvm" (-1)

All of the other Java tools (java, javac, jps, etc.) work just fine.

/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin indeed does not contain jvisualvm (all of a sudden).

/usr/libexec/java_home yields:

$ /usr/libexec/java_home
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

WTF?

Seems like a mixup of links; the /usr/bin/jvisualvm symlink points to something that does not exist (as people pointed out above). Apparently the jvisualvm executable (stub) exists and the way to fix this for now is to execute:

cd /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home/bin

sudo ln -s /System/Library/Java/Support/VisualVM.bundle/Contents/Home/bin/jvisualvm .

This requires sudo privileges and creates the missing symlink, pointing to the VisualVM bundle. No idea why it happened but upgrading to latest XCode 4.5.2 did not fix this for me automatically. I am running MacOS X 10.7.5 and java 1.6.0_37

It seems the supporting bundle got removed upon update. https://discussions.apple.com/thread/4474992?start=0&tstart=0

Download the bundle to use as a workaround. http://visualvm.java.net/download.html

EDIT:

Use this download link: https://java.net/projects/visualvm/downloads/download/release132/VisualVM_132.d‌​mg

I downloaded the visualvm (.dmg from java.net) and that works for me on my Mountain Lion.

For JDK 9+ users

> Starting with JDK 9, Visual VM will not be included with Oracle JDK. Developers who would like to use Visual VM with Oracle JDK 9 or later can get it from the Visual VM open source project site.

If you are already using NetBeans, another workaround is to use its profiler. In version 7.3:

• Start the Java application from the command line, desktop or [tag:javawebstart].

• In NetBeans, choose Profile > Attach Profiler.

• Select Attach to: <external Application>.

• Specify the desired analysis options.

• Click the Attach button.

• Choose the target application.

The Visual VM binary path for JDK 1.8 in macOS Mojave is

/Library/Java/JavaVirtualMachines/jdk1.8.0_231.jdk/Contents/Home/bin/jvisualvm

Basically,

/Library/Java/JavaVirtualMachines/<JDK_DIR>/Contents/Home/bin/jvisualvm

I can only run the .app version of JVisualVM on my mountain lion MBP

open /usr/share/java/Tools/Java\ VisualVM.app

VisualVM is also available as a standalone application. you can install it from https://visualvm.github.io/download.html

Sometimes it is very simple... you need to install visualvm via

sudo apt-get install visualvm

For locating the files, use

dpkg -L visualvm
