Steps: open heap dump -> compute retained sizes -> show Static Fields section -> the retained Field is empty for class
Fixed by http://hg.netbeans.org/profiler-main/rev/e360c9b38387.
Integrated into 'main-golden', will be available in build *201211060001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
