runtime(java): Improve the matching of contextual keywords Commit: https://github.com/vim/vim/commit/5ccdcc482e299609ae8852a75b22190e38b9b5df Author: Aliaksei Budavei <0x000c70@gmail.com> Date: Thu Apr 4 21:51:18 2024 +0200 runtime(java): Improve the matching of contextual keywords - Recognise a _record_ contextual keyword. - Recognise _non-sealed_, _sealed_, and _permits_ contextual keywords. - Admit _$_ to keyword characters. - Group _abstract_, _final_, _default_, _(non-)sealed_ (apart from _(non-)sealed_, the incompossibility of these modifiers calls for attention). - Remove another _synchronized_ keyword redefinition. I have also replaced a function with an expression. Before patch 8.1.0515, it should have been declared :function! to work with repeatable script sourcing; there is less to worry about with an expression.
