title: VisualVM memory leak detection
body: <p>I am trying VisualVM for detecting memory leak in java. I am using the version 1.2.1. I took two snapshots to try to capture the change of memory usage overtime. In a tutorial I read, it says that one can select there two snapshots and right click and select "compare". I followed this instruction, but could not find a "compare" option, It only allows me to "open" or "delete". Has anybody used VisualVM before? </p>
