Feedbacks from a CAP member:

* When I open two or more JVMs, jconsole creates separate internal
   frames for each JVM. But when I close some JVMs so I'm back to
   only one, jconsole doesn't allow to expand the single frame to use
   the entire window (without frame and border).

* Displays of large numbers, like heap sizes in bytes, should use
   separators for readability, i.e. 388.320.010 instead of 388320010.

* Provide menu option to clear all data collected so far for a
   VM, but without having to disconnect/reconnect.  And another
   option to change dynamically the -interval.

* The "Connect to Host" dialog should allow to pick a Java process
   from a combobox containing all JVMs found in the selected host.

* Please use the system look&feel, or at least provide an easy
   configuration allowing me to force it.  Even the JPI Control
   Panel has surrended to the system LAF...

* Provide buttons to hide/show each pane in the Memory and Classes
   tabs, just like in the Threads and MBeans tabs.

* In the Memory tab (at least), the line is not contiguous, it's a
   sequence of segments that don't connect perfectly.  This should
   be true in all graphs but it's more evident here.

* In the Memory tab, the graphis in the right side (esp. Non-Heap)
   are not correctly positioned, so they're cropped.

* The launcher shouldn't open a console.  To avoid this, I'm forced
   to use a shortcut: javaw.exe -jar C:\Java\JDK.150\lib\jconsole.jar
   but this shouldn't be necessary.
