Qustion about libnetty_tcnative_linux_aarch_64.so and libnetty_tcnative_osx_x86_64.jnilib

[Wangpeng(Forest,APM2.0)]

Hi Community:
        Some tool says there is a risk(CVE-2021-35940) in 
libnetty_tcnative_linux_aarch_64.so, libnetty_tcnative_osx_x86_64.jnilib and 
netty_tcnative_windows_x86_64.dll.
        I found the following fragment in pom.xml in apm-agent-core module:
                              <configuration>
                            <target>
                                <echo message="unjar" />
                                <unzip 
src="${project.build.directory}/${project.artifactId}-${project.version}.jar" 
dest="${project.build.directory}/unpacked/" />
                                <echo message="rename service providers in 
META-INF/services" />
                                <move 
file="${project.build.directory}/unpacked/META-INF/native/libnetty_tcnative_osx_aarch_64.jnilib"
 
tofile="${project.build.directory}/unpacked/META-INF/native/liborg_apache_skywalking_apm_dependencies_netty_tcnative_osx_x86_64.jnilib"
 />
                                <move 
file="${project.build.directory}/unpacked/META-INF/native/libnetty_tcnative_linux_x86_64.so"
 
tofile="${project.build.directory}/unpacked/META-INF/native/liborg_apache_skywalking_apm_dependencies_netty_tcnative_linux_x86_64.so"
 />
                                <move 
file="${project.build.directory}/unpacked/META-INF/native/netty_tcnative_windows_x86_64.dll"
 
tofile="${project.build.directory}/unpacked/META-INF/native/org_apache_skywalking_apm_dependencies_netty_tcnative_windows_x86_64.dll"
 />
                                <echo message="jar back" />
                                <jar 
destfile="${project.build.directory}/${project.artifactId}-${project.version}.jar"
 basedir="${project.build.directory}/unpacked" />
                            </target>
                        </configuration>
        Can anybody tell me how these three files are created? And how can I 
update them?
        Thank you very much!
