MAT is really good Tool to get clear picture of memory leak.
However I found in most of the result for top level dominator class loader it gives the result as

Label Number of Objects Used Heap Size Retained Heap Size Retained Heap, %
org.jboss.classloader.spi.base.BaseClassLoader 251,672 19,412,768 2,489,129,584 86.62%

It will be of great help if somebody would guide me to analyze the root cause for this.

Thanks in Advance.

I had a pleasure to work with MAT when we had memory problems with our server in my day job. It is a fantastic tool!

Its leak suspects quickly revealed where the problem is (in our case, jdbc driver was the culprit), and using thread view we quickly found out what happened. I am looking forward to using it again … although I hope that I will not need to
