The Java Mission Control (JMC) is a new JDK profiling and diagnostics tools platform for HotSpot JVM. It is a tool suite for basic monitoring, managing, and production time profiling and diagnostics with high performance. Java Mission Control minimizes the performance overhead that's usually an issue with profiling tools. This tool is a commercial feature built into the JVM and available at runtime.
The Java Flight Recorder (JFR) is a commercial feature. You can use it for free on developer desktops/laptops, and for evaluation purposes in test, development, and production environments. However, to enable JFR on a production server, you require a commercial license. Using JMC UI for other purposes on the JDK does not require a commercial license.
The Java Mission Control (JMC) consists of Java Management Console (JMX), Java Flight Recorder (JFR), and several other plug-ins downloadable from the tool. The JMX is a tool for monitoring and managing Java applications and the JFR is a profiling tool. Java Mission Control is also available as a set of plug-ins for the Eclipse IDE.
The following topic describes how to troubleshoot with Java Mission Control.
Java Flight Recorder and Java Mission Control together create a complete tool chain to continuously collect low level and detailed runtime information enabling after-the-fact incident analysis. Java Flight Recorder is a profiling and event collection framework built into the Oracle JDK. It allows Java administrators and developers to gather detailed low level information about how the Java Virtual Machine (JVM) and the Java application are behaving. Java Mission Control is an advanced set of tools that enables efficient and detailed analysis of the extensive of data collected by Java Flight Recorder. The tool chain enables developers and administrators to collect and analyze data from Java applications running locally or deployed in production environments.
The Java Flight Recorder does not trace every function call that gets executed. Instead, it 'samples' the application at regular intervals, collecting stack trace information about each thread being executed. So if you're looking for how many times a certain function is being called, or how much total time is spent executing a certain method, you're not going to find that kind of information. However, by analyzing the samples taken, you can still determine where your application is spending most of its time.
We'll assume, at this point, that Java 8 and Eclipse are already installed. If they are not, they can be found at the following locations:
Additionally, a couple of eclipse plugins, that contain the Java Flight Recorder and Java Mission Control tools, will need to be installed. This can be done within Eclipse by going to:
- Help -> Install New Software..
- In the 'Work with:' line, put:
- Select the 'Oracle Java Mission Control' option
- Help -> Install New Software..
- In the 'Work with:' line, put:
- Select the 'IDE Integration -> Flight Recorder Launch Configuration Tab' option
Once that's complete, create a simple java application that could use some optimization:
Create a Run Configuration for the java application:
- Run -> Run Configurations..
- Java Application -> New
Make sure the following two options are checked:
- Enable - This will create a flight recording of the running application
- Open recording - This will automatically open the flight recording when the application completes
Now run the application using the Run configuration. Once the application is finished, and the flight recording is open, we can see a lot of information about the running application.
- Select the Code tab on the left.
- From here we can see the packages and classes in which the application is spending its time.
- Select the 'Hot Methods' tab on the bottom (still within the Code tab on the left)
- Here we can see the methods in which the application is spending its time
- Select the 'Call Tree' tab on the bottom
- Here we can see the stack traces in which the application is spending most of its time
- Select the Memory tab on the left
- Select the Garbage Collections tab on the bottom (still within the Memory tab on the left)

- jabswitch – the Java Access Bridge. Exposes assistive technologies on Microsoft Windows systems.
- java – the loader for Java applications. This tool is an interpreter and can interpret the class files generated by the javac compiler. Now a
- single launcher is used for both development and deployment. The old deployment launcher, jre, no longer comes with Sun JDK, and
- instead it has been replaced by this new java loader.
- javac – the Java compiler, which converts source code into Java bytecode
- javadoc – the documentation generator, which automatically generates documentation from source code comments
- jar – the archiver, which packages related class libraries into a single JAR file. This tool also helps manage JAR files.
- javafxpackager – tool to package and sign JavaFX applications
