NetBeans Profiler has enhanced HeapWalker. Thread dump in the overview part of HeapWalker was extended to display
information about local variables, which are temporary GC roots. it is possible to navigate from a local variable to its corresponding instance in
the instance view and from Java Frame GC root in references view to a corresponding local variable in the thread dump.
This enhancement should help users to match Java Frame GC roots to a corresponding local variable.
