11992	Joining Overlapping Areas (Shift-J with two closed ways) results in RuntimeException	eladner	team	"==== What steps will reproduce the problem?
1. create two closed overlapping ways (I used the building tool, but any closed ways will do).
2. Select both ways.
3. Shift-J (Join Overlapping Areas)

==== What is the expected result?

Overlapping areas are joined into one closed way.

==== What happens instead?

One way is not split at all.  The second way is split into more pecies than necessary, resulting in more than two ways that need to be combined to form the complete outer way.

Occasionally, it will succeed, but I haven't been able to narrow down what the differences are (I tried different shapes with different starting points, inside, outside, etc for each way.  Some would fail while others would not).

==== Please provide any additional information below. Attach a screenshot if possible.
