Currently when your program stops at a breakpoint, hover on symbols will trigger evaluate DAP request automatically. And LSP doesn't receive hover request, so no way to show the javadoc during debugging.

Really like having a way to trigger the javadoc during debugging. It could be a shortcut to trigger javadoc manually. Or VS Code client intelligently determines sending the hover request to the correct server (DAP or LSP) based on the hover context. If the hover context is a variable, send to DAP, otherwise, to LSP.
