I also got this exception. I am using version 1.9 of metric reloaded. It failed when trying to calculate metrics on the whole project, but not smaller parts of it. I'm using java 8 and Intellij 2020.2.

I had a look at the code and I have a strong suspicion that this bug can be easily fixed by just not passing an empty string So instead of just checking for name != null in the following, also check that name.length > 0.

           if (name != null) {
                final Rectangle2D stringBounds = fontMetrics.getStringBounds(name, graphics);
                final double stringWidth = stringBounds.getWidth();
                if (stringWidth > maxFirstColumnWidth) {
                    maxFirstColumnWidth = (int) stringWidth;
                }
            }

From com.sixrr.metrics.ui.metricdisplay.MetricsDisplay.setColumnWidths(MetricsDisplay.java:242) where it calls java.desktop/java.awt.FontMetrics.getStringBounds(FontMetrics.java:532)

Same in IU-211.2924.
