LSP: Html4J UI modified work over LSP.
An attempt to rewrite html4j based refactoring UI for VSCode to work over LSP.
With be02cff one should be able to stop the Java execution before sending a message to VSCode:

And just by setting pause = true in the evaluation window the execution will then stop in chrome dev tools in VSCode:

The Change Refactoring UI seems to be working with generic and ko4j modules from https://github.com/apache/netbeans-html4j/commit/f031ed4df296ac3213dca79a32d4737c2bcbab26 - I'll prepare a release 1.8.1.
HTML/Java 1.8.1 is available on Maven central. @dbalek please replace 6c9ab9a with proper external binaries. I hope this will make it into NetBeans 15.
