javac generates spurious error messages for this test case:

record R(){
        public R throws Exception {}
}

R.java:2: error: <identifier> expected
        public R throws Exception {}
                ^
R.java:2: error: field declaration must be static
        public R throws Exception {}
                 ^
  (consider replacing field with record component)
R.java:2: error: invalid method declaration; return type required
        public R throws Exception {}
                        ^
Note: R.java uses preview language features.
Note: Recompile with -Xlint:preview for details.
3 errors

a better error message should be generated
