In case people are not aware, FastMath from Apache commons-math is a
pure Java implementation:

http://svn.apache.org/viewvc/commons/proper/math/trunk/src/main/java/org/apache/c
ommons/math/util/FastMath.java?view=markup

I ran the performance test in their test suite a few months ago and
published the results (note that I didn't write the performance test,
but I fixed some obvious micro-benchmark issues after they were
mentioned in the comments):
