aspecj accessing sun packages in java 11

Question

I am using ValidatorException class which is inside the package sun.security.validator.ValidatorException in java 11. But I am getting the following error :

AJC compiler errors: The type sun.security.validator.ValidatorException is not accessible

In maven compiler, i have fixed this problem using the compiler arguments --add-exports java.base/sun.security.validator=ALL-UNNAMED

but I don't know how to do with the AspectJ plugin.

Snapshot of my pom.xml for maven compiler

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <compilerArgs>
            <arg>--add-exports</arg><arg>java.base/sun.security.validator=ALL-UNNAMED</arg>
          </compilerArgs>
        </configuration>
        <executions>
          <execution>
            <id>default-compile</id>
            <phase>none</phase>
          </execution>
        </executions>
</plugin>

Snapshot my pom.xml for aspectj plugin

  <plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>aspectj-maven-plugin</artifactId>
    <version>1.7</version>
    <configuration>

          </weaveDirectories>

        <scope>system</scope>
        <systemPath>${project.basedir}/pom.xml</systemPath>
      </dependency>

      <dependency>

        <artifactId>aspectjrt</artifactId>
        <version>1.9.6</version>

        <groupId>org.aspectj</groupId>
        <artifactId>aspectjtools</artifactId>

      </dependency>

    </dependencies>
  </plugin>

Tried upgrading to the latest version of the plugin as well? Their [Github issues](https://github.com/mojohaus/aspectj-maven-plugin/issues) seems to be passive as well. At least the AspectJ [release notes, with 1.9.0](https://www.eclipse.org/aspectj/doc/released/README-190.html) states a way to perform what you desire. — Naman, May 20 '21 at 14:31

See

https://github.com/eclipse-aspectj/aspectj/pull/146#issuecomment-1079883826

https://github.com/mojohaus/aspectj-maven-plugin/issues/139

https://github.com/eclipse-aspectj/aspectj/issues/145

Examples using other two different packages that I needed for

      import sun.security.tools.keytool.CertAndKeyGen;
      import sun.security.x509.X500Name;

but you get the idea:

                <release combine.self="override"/>

                <compilerArgs>
                    <arg>--add-exports</arg>
                    <arg>java.base/sun.security.x509=ALL-UNNAMED</arg>
                    
                    <arg>--add-exports</arg>
                    <arg>java.base/sun.security.tools.keytool=ALL-UNNAMED</arg>
                </compilerArgs>
                <!-- this fixes: [142,6] error: cannot find symbol [ERROR]   symbol:   class sun.security.tools.keytool.CertAndKeyGen -->

                <source>${java.source.version}</source>
