Yes, I have noticed that. It is caused by commit 442438. I suggest first 
mention the commitment on the mailing list and then provide a patch.

The original code is:
assertEquals("Should return NaN", Double.NaN, Math.hypot(Double.NaN,
2342301.89843));

After the commit, it becomes:

assertEquals("Should return NaN", Double.NaN, Math.hypot(Double.NaN,
2342301.89843), 0D);


Thanks,
Mikhail
