Description
SLF4J: Class path contains multiple SLF4J bindings.

SLF4J: Actual binding is of type [ch.qos.logback.classic.util.ContextSelectorStaticBinder]当应用AppClassLoader中有logback时，sandbox启动时，会在应用的控制台日志中输出如上的信息，原因是SandboxClassLoader的parent为AppClassLoader，Slf4j在初始化时会扫描classpath下的实现类，这时会加载到应用中的资源；
建议是将SandboxClassLoader的parent设置为ext classloader。
