There are 2 issues addressed by the attached patch:
# Create platform aware (windows, Darwin, linux) implementations of CLibrary
(for instance CLibrary today assumes all platforms have support for
posix_fadvise but this doesn't exist in the Darwin kernel). If methods are
defined with the "native" JNI keyword in java when the class is loaded it will
cause our jna check to fail incorrectly making all of CLibrary "disabled" even
though because jnaAvailable = false even though on a platform like Darwin all
of the native methods except posix_fadvise are supported.
# Replace sigar usage to get current pid with calls to CLibrary/native
equivalent -- and fall back to Sigar for platforms like Windows who don't have
that support with JDK8 (and without a CLibrary equivalent)
--
