Error dialog while zooming into an area with many nodes

[ojschmidt@…]

While working with josm, an error dialog informed me that there was a programming error and that I could report it. I zoomed into an area with many nodes, but apart from that, I have no idea what exactly caused the error. The josm window is still open, and I can continue working with it without problems.
