I just run into the same problem.  Not sure why this happens as the MaximumFinder tries to get hold of the ResultsTable through the static method

                ResultsTable rt = ResultsTable.getResultsTable();

which calls the static method

                Analyzer.getResultsTable();


However, as a  work around, you can run the MaximumFinder as follows:

                IJ.run("Find Maxima...", "noise=50 output=List");

Curious what you found.  Can you post the relevant snippets?
