Springboot uses JarLauncher so that a nested jar is supported. But the agent code do not load class by using JarLauncher because it executes before the main method.As a result, the console will print

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation

--update This issue can reproduce the problem. https://github.com/libinglong/skywalking-threadpool-agent/issues/2
