   ### Actual behavior
   
   I have a thread that uploads a file to the server every 10 seconds, as time 
goes by, the heap memory will get bigger and bigger, and eventually the heap 
memory will occur out of memory:

   When I exported the heap memory, I found that there are a lot of objects of 
org.apache.sshd.sftp.client.fs.SftpFileSystem$Wrapper

   ### Expected behavior
   
   When the program is running normally, the heap memory will not overflow
