Description Jiri Sedlacek 2012-10-10 13:30:58 UTC 
Open the attached heap dump, click the Find button to compute first 20 objects by retained size. Exception is thrown:

java.lang.NullPointerException
 at org.netbeans.lib.profiler.heap.HprofHeap.computeRetainedSizeByClass(HprofHeap.java:653)
 at org.netbeans.lib.profiler.heap.ClassDump.getRetainedSizeByClass(ClassDump.java:130)
 at org.netbeans.modules.profiler.heapwalk.ClassesListController.getData(ClassesListController.java:181)
 at org.netbeans.modules.profiler.heapwalk.ui.ClassesListControllerUI$17$2.run(ClassesListControllerUI.java:879)
 at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:1454)
 at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:2036)

Works fine in 7.2.
