it seemed that mod_sftp.c has nothing do with proftpd session.

because we want upload multiple files simultaneously with only one connection which is limited by the server side.

we tested creating multiple remote directorys with one JSch channelSftp shared between multiple threads but failed, even we synchronized channelSftp mkdir method, proftpd got mixed requests and created wired directorys.

> @zrlw [This PR](https://github.com/proftpd/proftpd/pull/1501) should allow your configuration to work as desired, if you'd care to test it out... it works for us.

please upgrade nacos-client dependency to com.alibaba.nacos:nacos-client:1.4.0

原因是dubbo和nacos-spring-context依赖的com.alibaba.spring/spring-context-support版本不同而且不兼容所致，需要排除dubbo的依赖版本，但是不知道这样做有没有其他副作用。

发现有副作用，排除掉dubbo依赖的spring-context-support版本之后，注入dubbo的@Reference注解就会ClassCastException: java.lang.String cannot be cast to java.lang.Class ( DubboAnnotationUtils.java 95行）

根源是 alibaba的spring-context-support升到1.0.11并没有考虑向前兼容，AbstractAnnotationBeanPostProcessor新增的classValuesAsString，nestedAnnotationsAsMap默认为true，而当前所有dubbo版本的ReferenceAnnotationBeanPostProcessor依赖的是spring-context-support 1.0.10以及之前的版本，dubbo使用spring-context-support 1.0.11时需要将这两个值改为false。 我给dubbo提交了修订： apache/dubbo#8217
