Thanks a million for prividing such a good tools in solving my real life
problems. I have applied MAT in analysis of memory leak at work. It really
helps.
I follow instructions online and those blogs I can find in SAP. I still
got some problems with using this great tool during the time I am
searching memory leaks.
First one is why MAT provides two editors Histogram and Dominator_Tree and
what are they good for?
Second one is how the retained heap are calculated in two
editors(diagrams)as I found different componets stay on top in these two
diagrams when I try to group them by calss loader or by class , or by
package. It seems to me that the retained size in Dominator_Tree is
calculated by accumulating lagest objects according to their
classifications and for Histogram,I think the calcuation is by other means.
