19362	Infinite loop	Adrian	Don-vip	"I find that JOSM quite often gets into an infinite loop. This can happen at startup - see attached screenshot - or later on. The strange thing about this loop is that it runs in the background and it does not tie up all the processor cores. So JOSM remains usable, but it has a reduced amount of processing power available. Usually it is hearing the cooling fans start up, that alerts me that the loop has occurred. I have initiated this ticket while the infinite loop is in progress. The processor in my computer has four physical cores - eight virtual cores. Usually two or four virtual cores are tied up; in the screenshot it is four cores. The graph at the bottom of the Activity Monitor window shows the CPU load over about the last two minutes.

How can I collect more information to help in diagnosing the problem?
