Mind you some versions at least of Jikes generate a bad bit pattern for NaN:
FAIL $$java.lang.Double$$doubleToLongBits(double)long$$Value Double.NaN$$:
gnu.testlet.wonka.lang.Double.DoubleTest: doubleToLongBits(double)long
(number 9)
got -2251799813685248 but expected 9221120237041090560
NaN = fff8000000000000, but should be 0x7ff8000000000000
That's jikes 1.12, which was the last version to be able to compile Wonka
without generating bad code or dumping core ...
