Sorry for replying you so late. I run the same parameter as you do and I get the same "JarClassLoader: Warning". But it didn't prompt the Exception.
"-m 3" means that you choose the ILP method. It seems that you have not copied the lpsolve55.dll dynamic libraries correctly. You can refer to the Notice in README and it may help you.
