Lambdas with "final var" arguments result in error: did not generate token "final"

Processing lambda functions with arguments declared with final var produces: error: did not generate token "final"

Example Code:

class Test {

    public void test() {
        new File(".").listFiles((final var dir, final var name) -> true);
    }
}

$ java -jar google-java-format-1.17.0-all-deps.jar Test.java
Test.java:4:41: error: did not generate token "final"
