Failed to extractJni on MacOS for incorrect ClassLoader retried.

[yuqinghua]

In the method: BaseJniExtractor#extractJni , you retried to load resource with altLibName to adapt Darwin "jnilib or dylib" suffix. Lib Resource was loaded with libraryJarClass.getClassLoader on first time, but tried with this.getClassLoader() secondly.
You should load the libResource with libraryJarClass.getClassLoader consistently.
