---------------------------------------------------------
this library is downloaded by maven from official repository.
I checked the code of version 2.0.9
org.apache.mina.core.session.DefaultIoSessionDataStructureFactory
Line 165:
public Set<Object> getAttributeKeys(IoSession session) {
synchronized (attributes) {
return new HashSet<Object>(attributes.keySet());
}
}
double check the code of version 2.0.13, they are the same one.
And, I checked the jar file from Maven Repository, look into the file MANIFEST.MF, it shows that this jar is compiled under JDK 8

比较了一下，2.0.13版本内的代码是一样的。
另外，查看了一下从Maven Repository上下载下来的MANIFEST.MF文件，的确是使用JKD8编译的：
