The class loader explorer displays the parents of class loaders. Sometimes it is useful to display the class loaders as a tree, so expanding a loader gives the children.
I have some code to enhance the class loader explorer with a -tree option to display the loaders as a tree. I have also made the explorer examine a set of loaders if required rather than all of them, by specifying the loaders or classes loaded by the loaders or instances of classes loaded by loaders.
The enhancement has been made. Here is an example of the output: Class Name | Defined Classes | No. of Instances --------------------------------------------------------------------------------------------------------------------------------------------------------- | | com.ibm.oti.vm.BootstrapClassLoader @ 0x480ee0 | 15,597 | 117,703 sun.misc.Launcher$ExtClassLoader @ 0x483bb8 | 217 | 143 |- parent sun.misc.Launcher$AppClassLoader @ 0x48b200 | 3,885 | 1,870 | |- parent org.mortbay.start.Classpath$Loader @ 0x4eb458 | 837 | 115 | | |- parent Cometd Test WebApp | 482 | 125 | | |- parent Test WebApp | 82 | 8 | | |- parent Test WebApp | 82 | 8 | | |- parent /leak | 6 | 3 | | | |- demo.LeakServlet | | 1 | | | |- demo.LeakServlet.doGet(Ljavax/servlet/http/HttpServletRequest;Ljavax/servlet/http/HttpServletResponse;)V| | 1 | | | |- demo.LeakServlet.getOtherChars()[C | | 1 | | | |- demo.LeakServlet.<clinit>()V | | 0 | | | |- demo.LeakServlet.<init>()V | | 0 | | | |- demo.LeakServlet.getChars()[C | | 0 | | | '- Total: 6 entries | | | | |- parent JAAS Test | 0 | 0
