有时候会用不同的用户启动服务端，碰到这个错误
java.lang.NoClassDefFoundError: Could not initialize class com.baidu.bjf.remoting.protobuf.utils.JDKCompilerHelper

后来发现是因为/tmp/JPROTOBUF_CACHE_DIR/ 这个文件夹下有文件权限不足导致，权限设置好或者删掉之后就正常了。

想请问一下，为啥是先报一个java.lang.NoClassDefFoundError:的错误，后边再报权限不足呢？JDKCompilerHelper这个类jar包中肯定是有的。

另外/tmp/JPROTOBUF_CACHE_DIR/这个目录是不是每次执行都重新创建好些？

错误信息如下：

嗯，这个在spring boot下，会有这个操作， tmp目录是从 环境变量 System.getProperty("java.io.tmpdir") 获取的，也可以通过环境变量来修改目录，也可以提前创建
