When invoking heap.livepaths() to get all the paths from GC roots to a particular instance many of those paths are omitted due to the bug in the reference-walking algorithm. Thus, the user receives incomplete and false information.
Integrated into 'main-golden', will be available in build *201103020001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
