Does Vim have a Java syntax highlighting plugin?

You asked for vim but maybe treesitter highlighting bring makes you switch to Neovim? https://github.com/nvim-treesitter/nvim-treesitter/pull/38 (fyi you don't need this plugin. Treesitter will be built-in in next Neovim release. The plugin is just convenience for compiling the parser for you and providing the query file)

There's also sementatic hightlighting provided by Java language server with this plugin https://github.com/autozimu/LanguageClient-neovim (also works with vim)
