## Method Details

### isParentClassLoader

static boolean isParentClassLoader(ClassLoader parent, ClassLoader child)
Utility method to check if some class loader is a (grand-)parent of or the same as another one. This means the child will be able to load all classes from the parent, too.

If caller's codesource doesn't have enough permissions to do the check, `false` is returned (this is fine, because if we get a `SecurityException` it is for sure no parent).
