ISPN-4505 Now using @Override for methods which couldn't be marked properly before
ISPN-4505 Document the fact we dropped compatibility with older Lucene versions
ISPN-4278 Add QOP support to the HotRod SASL implementation
Replace sfl4j-jdk14 dependency with sfl4j-log4j12 so that jboss logging

Add more debugging around cache listeners. It seems Class.getMethods()
sometimes returns synthetic methods created by overriding a generic method.
