Description

For v2.9.1 inside org.apache.logging.log4j.util.LoaderUtil and getClassLoaders() method we have lines 120-123 as such:

ClassLoader parent = tcl;
while (parent != null && !classLoaders.contains(parent))

{ classLoaders.add(parent); }

where it looks like some getParent() call is either missing or otherwise "while" loop is not needed.

In line 111 tcl classloader already added into list of clasloaders:
classLoaders.add(tcl);

Was it an attempt to add all classloaders hierarchy or just some immediate parents?
