In org.eclipse.birt.chart.render.BaseRenderer at line 1274 there's this comment:

		// TODO: label text may be changed in script,
		// in such the ellipsis may need to be recalculated

This bit me when I tried to reduce the size of the legend label in beforeDrawLegendItem.  The BIRT code obtains the truncation index based on the legend label before the event and then attempts to do a substring after the event without checking the index.  I worked around the problem by appending spaces to the end of the string so it remained the same length, but it ought to be fixed.

Reproducible: Always
