typo in JConsole's MemoryPoolStat.getAfterGcUsage()

[曹旭东]

Hi all,

I've found a typo in JConsole's MemoryPoolStat.getAfterGcUsage(), which is
returning the wrong field. Here's a patch to fix it:

diff -r 9e82ac15ab80

     public MemoryUsage getAfterGcUsage() {
-        return beforeGcUsage;
+        return afterGcUsage;
     }
 }

In addition, I searched "MemoryPoolStat" in JConsole's source code, and I
got a method "getStat" in
"src/share/classes/sun/tools/jconsole/MemoryPoolProxy.java", which could
generate an MemoryPoolStat object. But when searching
"getStat", I got nothing.  So my question is that,  have
class MemoryPoolStat not been used yet, or dose it be used in other jar?

Thanks,
