Atualmente, estou tentando mover nosso aplicativo do Java 8 para o Java 10 e em alguns meses passarei para o Java 11.

Temos um sistema legado que usa um pouco de APIs que são removidas ou serão removidas, eu acho. Estamos usando o script ant (1.10.1) para a compilação de aplicativos.

Abaixo está o mesmo da parte que cria nosso aplicativo:

  <target name="javac-setup" depends="flags, with.clover, jaxb-apply, flamingo.javac"/>

 ,   <target name="javac" depends="javac-setup">
        <mkdir dir="${workmanager.dir.classes}"/>
        <javac destdir="${workmanager.dir.classes}" deprecation="on" debug="${javac.debug}" encoding="iso-8859-1" includeantruntime="false">
            <compilerarg line="-Xlint:static"/>
            <compilerarg line="-Xlint:unchecked"/>
            <compilerarg line="-Xlint:overrides"/>
            <compilerarg line="-Xmaxerrs 9999" />
            <compilerarg line="-Xmaxwarns 9999" />
            <compilerarg value="-Werror"/>
            <src path="${workmanager.dir.src}"/>
            <src path="${webservices.dir.java.src}"/>
            <patternset refid="java.sources"/>
            <classpath refid="classes.classpath"/>
        </javac>
    </target>

Durante a compilação, estou recebendo alguns erros relacionados ao Java Swing (novamente um pouco mais antigo, mas preciso viver com ele) depois de passar para o Java 10. Como ainda não estou completamente ciente de todas as mudanças ocorridas no Java 10, para mim parece como a questão está relacionada ao conceito de modularização. Não tenho certeza, embora ainda esteja aprendendo. Conheço sua sugestão para saber se esses tipos de erro estão relacionados à modularização. Também alguma sugestão ou dicas para corrigir isso?

Abaixo está o erro:
