getClassLoader

public ClassLoader getClassLoader()

Returns a classloader containing the only jars in this JarState. Look-up of classes in the org.slf4j package are not taken from the JarState, but instead redirected to the class loader of this class to enable passthrough logging.
The lifetime of the underlying cacheloader is controlled by SpotlessCache.
