Description

Reports empty static { } initializer blocks inside class declarations.

Rationale

An empty static initializer block is dead code. It performs no initialization and adds syntactic noise to the class definition. It usually indicates that a developer started writing static setup code and either forgot to complete it or moved the logic elsewhere without cleaning up.

// Bad -- empty static initializer
public class Config {
    static {
    }
}

Remediation

Add the intended initialization code or remove the empty block entirely:

// Good -- static initializer with content
public class Config {
    private static final Map<String, String> DEFAULTS;
    static {
        DEFAULTS = loadDefaults();
    }
}
