Strictly speaking this is not actually a memory leak as the additional memory use is bounded - memory use does not go up forever. The application is creating and disposing a lot of ClassLoaders via OSGi (Apache Felix) with Spring OSGi. Are there any known GC memory leaks caused by ClassLoaders being dropped for instance? according to "the rules" there is no heap root).
No known memory analysis tool can find the heap root (i.e. jQuery, jQuery UI, jQuery form Validation, jQuery custom Plugins, Ajax. It seriously affects runs of our functional test suite. Tomcat, Apache Web Server, Apache Solr, Eclipse, JProfiler, LDAP, ERwin.

In practice this doesn't hurt a standard JIRA customer as a full system import is generally a one-off operation. This happens on all JVMs we have tried so far, which are the 1.5 and 1.6 JVMs on Linux and Mac, and the IBM 1.6 JDK on Linux. There are no JNI Global references either, yet this memory remains uncollectable! Starting with all strong references and proceeding to remove soft and weak references - even things like clearing the cache - and even Finalizer references until YourKit, Eclipse MAT, JProfiler and jhat profilers all report that the memory in question is dead and should be collectable, but inexplicably the JVM still holds on to it.
In the process of diagnosing this we have tracked down and removed every possible reference to a large section of memory (a plugin framework) that we could find. There is not a one-one correspondence to restarts and leaks however (we generally see about 6 dead plugin systems although 30 or more restarts may have occured). The plugins do not have to have been used for the leak to occur. Restarting Plugins2 (in JIRA this happens when doing a full system import) when there are active Plugins2 plugins does not allow all memory previously referenced to be available for GC, most particularly there are a number of ClassLoaders left active with no obvious GC root the classes of whom are themselves roots for a whole graph of circularly referenced garbage. This will allow VisualVM to recognise it and you can proceed to run it as normal.The Plugins2 system in JIRA4 appears to be leaking heap and permgen when restarting it.

If this is the case, you can set a breakpoint in your code and run it in debug mode. Note: If your application executes and ends extremely quickly, VisualVM might not pick it up in time. Now run your application and you’re good to go! Edit one or both to have the preferred launcher as VisualVM. If you now go to Default Launchers in the same location, you can set Run and Debug configurations for your Java Application. Navigate to VisualVM Configuration in Preferences where you can set your JDK (make sure it is not the JRE) and then set the executable to the jvisualvm.exe in your JDK’s bin folder. Select it and hit Next. Follow the instructions on screen and Eclipse will restart.

If you now return to the Install Software dialog you should see the launcher feature available to install. Find your VisualVM launcher folder and select it. Launch Eclipse and click ‘Help’ -> ‘Install New Software…’.Ĭlick ‘Add.’, fill in a name and then click ‘Local’. Eclipseĭownload the VisualVM launcher for Eclipse and extract it to a location of your choosing. Idea will now have buttons for launching or debugging with VisualVM. Set the path to your jvisualvm.jar file which should be in your JDK’s bin folder. Relaunch Idea and go to the new VisualVM Launcher settings page.
Open up the plugins settings page and install it by selecting ‘Install plugin from disk’. To set up VisualVM in Idea, first download the VisualVM Launcher jar.

So here’s how to do it for IDEA and Eclipse. Further to this, it’s actually an evolution of Netbeans’s profiler, which was first introduced in 2004.Īll of the major IDEs used by Java developers – with the exception of Netbeans due to its integrated profiler – can quickly be set up to use VisualVM.

What you might not realise is that you almost certainly have VisualVM installed – it’s been included as a standard part of the JDK since Java 1.6 update 7. We use it to help development of our products BuildVu, FormVu, JPedal, and JDeli. It also has tools for tracking threads, interacting with garbage collection, and monitoring memory and CPU usage. It’s hard to put a label on VisualVM – it has a profiler, but it’s more than that. He's also enjoyed working with SVG, Java 3D, Java FX and Swing.
