A simple Windows program to test the new GeographicTransformation class available in ArcGIS Runtime 10.2, yields UnsatisfiedLinkError.  The same program also calls a method in SpatialReference.  It yields good result.  The environment is set correctly.  Otherwise, the SpatialReference method would not work either.
The code snippet:
    GeographicTransformation gt = GeographicTransformation.create(gtTable);
causes the following exception:
Exception in thread "main" java.lang.UnsatisfiedLinkError: com.esri.core.geometry.GeometryEngineCore.nativeGetGeoTx(ILjava/lang/String;Z)Ljava/lang/String;
