   Note from Slack conversation - one of these usages is registering NetBeans' editor kits for use with JEditorPane::setContentType. This may not be feasible in future. This is currently done by registering a HackMap subclass of HashTable in the AppContext that can lazily lookup editor kits. Using the supported registration APIs to eagerly register might need to be done within each providing module, or by listening to module enablement, to handle module loading, ergonomics, etc.

   Assuming we don't do further hacks, we might want to note that registration of NetBeans' editor kits / expectation is deprecated in the notes for NB31?

   planning to add a warning log line which prints some useful info if the hack is active + a flag which turns the hack off. Somewhat inspired by how the JDK removes deprecated features. Thought about only enabling it for platform apps but I believe it could be always enabled. #9721
