Firstly attempts to load the library from java.library.path, if that fails then it falls back to extracting the library from the classpath loadLibraryFromJar(java.lang.String)

参数:

tmpDir - A temporary directory to use to copy the native library to when loading from the classpath. If null, or the empty string, we rely on Java's File.createTempFile(String, String) function to provide a temporary location. The temporary file will be registered for deletion on exit.

java.io.IOException - if a filesystem operation fails.
