In addition to the consensus we have regarding 1.1.7_08a on 2.5.1, I just tested
the same case on 2.6 using 1.1.7_08a. The Total Memory is not reducing at all.
However, the Free Memeory could get increased as time goes. Meaning, the VM is not
releasing memory back to the os but instead, make it available for its own usage.

cu tested on jdk 1.1.7, 1.1.8 and on 1.2.1_04 but still getting the same . He tested on NT as well as on Solaris platform but getting the same.
