If I add [1] to PATH, I do not need to call the System.load method. However,
if I move the dll to another folder and add that folder to PATH, then it
does not work. Then I again need the System.load method call to the original
path [2].
So, my compiled version of openbabel_java.dll references [2] while the
version from 2.3 references [3]. I guess this is the source of the problems
because when using the 2.3 version earlier, the folder of [3] (the install
folder of 2.3) was automatically added to PATH. Hence, I was never even
aware that openbabel-2.dll was being used by openbabel_java.dll.
