A DESCRIPTION OF THE PROBLEM :
When using the `String.format` method in JDK 11, if the width specified in the format specifier exceeds `Integer.MAX_VALUE` (i.e., 2147483647), an `IllegalFormatWidthException` is expected to be thrown. This behavior is documented in the official document ([Source](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/util/Formatter.html)):

> "If the format specifier contains a width or precision with an invalid value or which is otherwise unsupported, an `IllegalFormatWidthException` or `IllegalFormatPrecisionException` will be thrown."

However, in JDK 11, this exception is not thrown when the width exceeds `Integer.MAX_VALUE`. Instead, the error is silently ignored due to the `assert(false)` statement in the `width` method ([Source](https://github.com/openjdk/jdk/blob/jdk-11%2B25/src/java.base/share/classes/java/util/Formatter.java#L2814)). As a result, the method returns an incorrect value of `-1`, leading to erroneous outputs.






STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Version Information: JDK Version: OpenJDK 11.0.25
Code Example:
public class TestFormat {
    public static void main(String[] args) {
        String formatted = String.format("%2147483648d", 123);
        System.out.println("Formatted Value: " + formatted);
    }
}

Compilation and Execution Commands:
javac TestFormat.java
java TestFormat


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
An `IllegalFormatWidthException` should be thrown.
ACTUAL -
 `Formatted Value: 123`

FREQUENCY : always
