I don't know the full history of it (perhaps mjw can shed some more
light), but as far as I'm aware, the Java StrictMath methods in GNU
Classpath were written as exactly this: Java versions of the fdlibm
code.  Developers of Java-based VMs such as JNode and JikesRVM
preferred these, because they didn't have to incur the cost of
dropping out to native code.
