Both the addPropertyChangeListener(PropertyChangeListener and removePropertyChangeListener(PropertyChangeListener were deprecated in Java 8 and removed in Java 9. There are two new replacement methods addConfigurationListener(Runnable) and removeConfigurationListener(Runnable) that have been added as replacements.

For the JBoss Log Manager these could likely be no-ops like the originals were.

In Java 9 to updateConfiguration() methods were added as well. These should also be overridden with no-ops.
