Difference between JDK 6 & 7 on Native Memory usage

Hi All,

We saw few weird behavior in JDK 1.7 memory usage. When we run "top"
command it shows JVM consuming native (resident) memory more than JDK 1.6.
And it keeps rising up.  We do understand we have a memory leak, but why
are seeing this more in JDK 1.7 compared with JDK 1.6?

Is there a specific difference between JDK 1.6 & 1.7 to explain this?

Thanks
Arun
