Unexpected handling of lines with less than 100 characters

Reproduza o problema com test.java usando a invocação de linha de comando de google-java-format-1.9-all-deps.jar mostrada no relatório, comparando as saídas anterior, posterior e esperada. Rastreie o comportamento do formatter para strings SQL multilinha; considera-se concluído quando apenas a linha longa demais é dividida, enquanto as outras linhas mais curtas mantêm sua formatação original.

I have some quite large sql multiline string and when one line is over 100 characters it will re-format it onto 2 lines. While I believe this is the correct behaviour to split this long line, it also re-formats all of the other lines of the String which I don't think should happen as they are under 100 characters long, therefore I think this is a bug.

NB: Because of https://github.com/google/google-java-format/issues/566 you can only see this happening using the jar on the command line as per the example below:

before - unformatted file:

package x;

public class test {

  static final String MY_SQL_QUERY =
      "SELECT "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  l.some_really_long_column_name    AS some_really_looooooooooooooooooooong_column_name, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, ";

  public test() {
    int x=1;if(x==1){x=2;}else{x=3;}
  }

}

apply google java formatting:

/tmp $ java -version
openjdk version "11.0.9" 2020-10-20
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.9+11)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.9+11, mixed mode)
/tmp $ cksum ~/lib/google-java-format-1.9-all-deps.jar

/tmp $ java -jar ~/lib/google-java-format-1.9-all-deps.jar ./test.java

after - formatted by google java formatter:

package x;

public class test {

  static final String MY_SQL_QUERY =
      "SELECT   customer_id             AS customer_id,   customer_id             AS customer_id, "
          + "  customer_id             AS customer_id,   customer_id             AS customer_id,  "
          + " customer_id             AS customer_id,   l.some_really_long_column_name    AS"
          + " some_really_looooooooooooooooooooong_column_name,   customer_id             AS"
          + " customer_id,   customer_id             AS customer_id, ";

  public test() {
    int x = 1;
    if (x == 1) {
      x = 2;
    } else {
      x = 3;
    }
  }
}

Expected - this is what I think google java formatter should do:

package x;

public class test {

  static final String MY_SQL_QUERY =
      "SELECT "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, "
          + "  l.some_really_long_column_name    "
                 + "AS some_really_looooooooooooooooooooong_column_name, "
          + "  customer_id             AS customer_id, "
          + "  customer_id             AS customer_id, ";

  public test() {
    int x = 1;
    if (x == 1) {
      x = 2;
    } else {
      x = 3;
    }
  }
}
