Don't worry about it, we share most of the bugs and it is good to learn about
cross-project issues. You would be surprized how often a bug in one runtime
also manifests itself in some way in other runtimes.

In GNU Classpath this code goes through the VMDouble class in
vm/reference/java/lang/VMDouble.java. There is a reference implementation for
POSIX/JNI systems of the "native" methods in
native/jni/java-lang/java_lang_VMDouble.c which uses the math library functions
in native/fdlibm.

IKVM has its own implementation of VMDouble (which doesn't use JNI/C).
