+         - it's set as a Component's current lookandfeel; or
+         - there's a WeakReference to it somewhere else in your code
+
+       Generally the fix for this will be to make sure you call
+       Component::setLookandFeel (nullptr) on any components that were still using
+       it before you delete it, or call LookAndFeel::setDefaultLookAndFeel (nullptr)
+       if you had set it up to be the default one. This assertion can also be avoided by
+       declaring your LookAndFeel object before any of the Components that use it as
+       the Components will be destroyed before the LookAndFeel.
+
+       Deleting a LookAndFeel is unlikely to cause a crash since most things will use a
+       safe WeakReference to it, but it could cause some unexpected graphical behaviour,
+       so it's advisable to clear up any references before destroying them!
