SkyWalking faces a break in byte-buddy upgrade from 1.10.19 to latest 1.11.16

Hi

This upgrade operation is initiated in https://github.com/apache/skywalking-java/pull/30, which doesn’t show any compiling level issue. But after I submitted pull request, and some issues show up in the plugin tests. Those plugin tests are really loading the latest agent(depend on 1.11.16) and running a real service.

According to this CI logs, https://github.com/apache/skywalking-java/pull/30/checks?check_run_id=3661574946

As I check locally, org/apache/skywalking/apm/dependencies/net/bytebuddy/implementation/LoadedTypeInitializer is in the shaded package. You also could download it from our CI cached artifacts, https://github.com/apache/skywalking-java/suites/3826509443/artifacts/94739312

The test application’s source codes are here, https://github.com/apache/skywalking-java/tree/main/test/plugin/scenarios/jdk-http-scenario, which is compiled through JDK1.8
