Answer 1

The above screenshot is looking at incoming references by class, which is interesting but the more common way to investigate a leak is to run Merge Shortest Paths to GC Roots: this will tell you what is keeping your objects alive. MAT will never be able to point you to a specific line number as it only shows the object reference graph (unless you use the Java Basics > Thread Overview and Stacks query and find a problem on a particular frame).
