JAVA.TYPE.MPSFA : Mutable Public Static Final Array (Java)

JavaScript is not currently enabled, but is required for full CodeSonar manual search and browse functionality.

If you are viewing this file in your hub's Web GUI, enable JavaScript in your browser: you will also need it for GUI functionality.

If you opened this file directly from disk, your browser may be directly suppressing JavaScript functionality: certain browsers perform this suppression on local files (but not files delivered by web servers) for security reasons.

If you access the manual through the hub's Web GUI, the functionality will not be suppressed because the hub is a web server.
Alternatively, your browser may allow you to explicitly disable the security setting that suppresses functionality. See the CodeSonar FAQ for more information.

An array is declared as public final static, but its contents can be modified.

The final constraint requires that the array object itself be assigned only once, but makes no guarantees about the values of the array elements.

The public modifier exposes the array outside the class: a malicious program can change the values stored in the array.

Use annotation @Immutable to identify classes that should be ignored by this check because they only undergo mutations that do not change observable behavior.

有効/無効設定

このワーニングクラスのチェックはデフォルトで有効になっています。チェックを無効にするにはプロジェクト設定ファイル（configuration file）に以下の WARNING_FILTER ルールを追加してください。

WARNING_FILTER += discard class="Mutable Public Static Final Array (Java)"

// MyClass.java
public class MyClass {
    public final static int[] SMALL_PRIMES = new int[] { 2, 3, 5, 7, 11, 13, 17 };
    // 'Mutable Public Static Final Array (Java)' warning issued on previous line:
    // - array is final but its elements are not 
}

Hide the field, for example by reducing its visibility to protected.
