Hi Adam,
most panels in ImageJ are "singletons", i.e., ImageJ has only one
instance. It would be confusing for the user to see two ROI Managers
or two "Brightness&Contrast" panels: which one is the correct one?
Plugins can create their own instances of some panels, including the
ResultsTable, e.g. to avoid interfering with that of ImageJ (in that
case, one should set a custom title, different from "Results").
ResultsTable.getResultsTable(), equivalent to Analyzer.getResultsTable
() should give you the one used by ImageJ.
Also the MaximumFinder uses ResultsTable.getResultsTable().
