java/lang/Math/HyperbolicTests.java fails with

Failure for Math.tanh(double):
        For input -0.0 (-0x0.0p0)
        expected -0.0 (-0x0.0p0)
        got 0.0 (0x0.0p0);
        difference greater than ulp tolerance 0.0 or the result has larger magnitude than 1.0
Failure for StrictMath.tanh(double):
        For input -0.0 (-0x0.0p0)
        expected -0.0 (-0x0.0p0)
        got 0.0 (0x0.0p0);
        difference greater than ulp tolerance 0.0 or the result has larger magnitude than 1.0
Math.tanh() is actually implemented in the libraries, not in the JVM, so transferring the bug.
