spotless-maven-plugin: <toggleOffOn/> breaks <forbidWildcardImports/>

Reproduce el problema con la configuración mínima de pom.xml y src/test/java/org/example/ImportMess.java usando mvn spotless:check, comparando primero el comportamiento con y sin . Rastrea los pasos de formateo de Java para toggleOffOn, removeUnusedImports y forbidWildcardImports; se considera completado cuando ambas comprobaciones informan de sus infracciones esperadas sin que una suprima o sustituya a la otra.

It seems as though adding <toggleOffOn/> somehow interferes with `

Consider the following minimal configuration:

    <build>
        <plugins>
            <plugin>
                <groupId>com.diffplug.spotless</groupId>
                <artifactId>spotless-maven-plugin</artifactId>
                <version>3.1.0</version>
                <configuration>
                    <java>
                        <toggleOffOn/>
                        <removeUnusedImports/>
                        <forbidWildcardImports/>
                    </java>
                </configuration>
            </plugin>
        </plugins>
    </build>

And the following source code:

package org.example;

import java.util.*;
import java.sql.PreparedStatement;

public class ImportMess {
}

With this configuration, running mvn spotless:check will fail on the <removeUnusedInports>:

But if you remove <toggleOffOn/>, it will now fail on the <forbidWildcardImports/>:

Note:
The <removeUnusedImports/> isn't really important here, I added it just to demonstrate that the project structure is correct and spotless is actually picking up something from that file.
