You can't access com.sun packages without explicitly setting them on your compile options. After adding --add-exports=java.base/com.sun.crypto.provider=ALL-UNNAMED to compilerArgs it compiles without any error.

Code:

   Security.addProvider(new com.sun.crypto.provider.SunJCE());

Maven:

    </properties>

                    <target>11</target>
                    <compilerArgs>
                        <arg>--add-exports=java.base/com.sun.crypto.provider=ALL-UNNAMED</arg>
                    </compilerArgs>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

java.security.Security.getProviders() returns you all the providers including the SunJCE.

   Stream.of(java.security.Security.getProviders()).forEach(System.out::println);

So better option to get the SunJCE instane is java.security.Security.getProvider("SunJCE")
