+      The Eclipse Memory Analyzer is a tool that helps you find memory

+      analyze productive heap dumps with hundreds of millions of
+      objects, quickly calculate the retained sizes of objects, see
+      who is preventing the Garbage Collector from collecting objects,
+      run a report to automatically extract leak suspects.
