We tested the Legends with a group plot and it worked fine for us. If you are passing in a group plot object, you do have to use the AddLegendItem method that specifies a group number, though, numbers 0, 1, 2, and 3 below.
legend.addLegendItem("Prozac", ChartConstants.HBAR, thePlot2, 0, legendFont);
legend.addLegendItem("Zoloft", ChartConstants.HBAR, thePlot2, 1, legendFont);
legend.addLegendItem("Paxil", ChartConstants.HBAR, thePlot2, 2, legendFont);
legend.addLegendItem("Celexa", ChartConstants.HBAR, thePlot2, 3, legendFont);
Or you can just use the addLegendItem overloads where you explicitly set the color attribute, rather than use a lookup of the plot objects color attribute. They all seem to work.
If you can't figure it out show the code you used creating the legend with the MultiLinePlot.
How do I get a legend to show colors?
