Description

Currently MAT does not recognize the fact that "WeakHashMap" is not the only dominator of the values that are stored in the map.

In other words, it might realize that if all strong reference to the key are gone, the value would go away.

It makes sense to support that in calculation of dominator tree.
Additional support might be needed for some well-known weak/soft collections.
