            Bug ID: 3082
           Summary: Don't reload heap dump if already loaded into view.
           Product: Thermostat
           Version: hg
          Hardware: x86_64
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: gui
          Assignee: unassigned at icedtea.classpath.org
          Reporter: jkang at redhat.com
                CC: thermostat at icedtea.classpath.org

In gui users can load a heap dump into view by double-clicking the marker in
the heap dump graph or by double-clicking the item in the list. This shows the
heap tree map among other things.

When having a heap dump in view, double-clicking either will result in the gui
loading that heap dump again, even though it is already in view.

Reproducer in GUI:
1. Create heap dump
2. Select heap dump for viewing
3. Select heap dump again

Expected:
Nothing happens.

Actual:
The heap dump is fully reloaded into view.


There should also be some sign of which heap dump is currently loaded.
