The new Java viewer can use libjpeg-turbo through JNI to speed up JPEG decoding by a factor of 2-4x, so that library is not strictly required, but it is required in order to achieve full performance. The JNI library is packaged with the Mac application bundle, since the Java viewer is being used as a self-contained app on that platform. There are two copies of libturbojpeg because older Mac Java implementations (for instance, on Tiger) used .dylib as the default suffix for JNI libraries, but newer ones expect the library to have a suffix of .jnilib. On non-Mac platforms, you would need to download and install the 1.3 pre-release libjpeg-turbo SDK for now (http://www.libjpeg-turbo.org/DeveloperInfo/PreReleases) in order to take advantage of accelerated JPEG decoding.
