Retention path of an object always starts with a GC root. From the point of Garbage Collector, root is a reference to an object that must not and will not be collected. This makes roots the only possible starting point for building retention graphs. Understanding root types can be extremely important during the "Who retains the object?" analysis.

The context menu contains the following commands: Navigate to Largest Memory Retainers' Tree - activates the Largest Memory Retainers view and locates the object in it. Open diagram starting from this instance - opens the …
GC Roots -- what are they?

Short answer -- you shouldn't be worried by objects that are only retained by V8's GC roots. Assuming that Chrome and V8 don't have bugs (ahem!), they will be released sooner or later. If you are developing a web application, you need to worry only about references that you create yourself, and they are usually traceable to window objects and dom trees.
Garbage Collection (GC) - Eclipse

A root object is an object that is accessible from outside of the heap such as a stack, class static field, or JNI reference. For other objects in the heap to be reachable, they must retain a connection from a root object. In the initial step, tracing identifies all root objects by running a root scan.

Tracing garbage collection is the kind which keeps track of which heap objects are directly reachable (“roots”), figures out the whole set of reachable heap objects (“tracing”, also, “marking”), and then cleans them up (“sweeping”). Throughout this blog post I will use the term “GC” to refer to tracing garbage collection/collectors unless otherwise stated 1.

The GC traces reachable objects starting from root objects also known as GC roots. A GC root is a pointer into a memory pool from outside that memory pool, i.e. an object that is accessible from outside the heap.

目前主流的虚拟机都是采用GC Roots Tracing算法, 比如Sun的Hotspot虚拟机便是采用该算法, 该算法的核心算法是从GC Roots对象作为起始点, 利用数学中图论知识, 图中可达对象便是存活对象, 而不可达对象则是需要回收的垃圾内存, 这里涉及到两个概念: GC Roots, 可达性.
Tracing garbage collection - Wikipedia
https://en.wikipedia.org/wiki/Tracing_garbage_collection
In computer programming, tracing garbage collection is a form of automatic memory management that consists of determining which objects should be deallocated by tracing which objects are reachable by a chain of references from certain "root" objects, and considering the rest as "garbage" and collecting them. Tracing garbage collection is the most common type of …

Tracing collectors will determine the objects' reachability by tracing them from a set of root objects, known as GC roots. If an object is reachable from a root object, either directly or indirectly, then it will be considered alive. Others are unreachable and candidates for collection:
