this is the case that the generated bytecode of instrumentation method exceeds limit, org.jfree.chart.plot.PiePlot3D#drawSide(Ljava/awt/Graphics2D:Ljava/awt/geom/Rectangle2D:Ljava/awt/geom/Arc2D:Ljava/awt/geom/Area:Ljava/awt/geom/Area:Ljava/awt/Paint:Ljava/awt/Paint:Ljava/awt/Stroke:ZZ)V Although the stacktrace is printed out, the error is actually ignored.
