AWS SFTP: EOF while reading packet with version 0.32.0

[pimenas]

Hello,

After upgrading to 0.32.0 we get the following exception when trying to upload to AWS SFTP service:

EOF while reading packet
net.schmizz.sshj.sftp.SFTPException: EOF while reading packet
	at net.schmizz.sshj.sftp.PacketReader.readIntoBuffer(PacketReader.java:55)
	at net.schmizz.sshj.sftp.PacketReader.getPacketLength(PacketReader.java:60)
	at net.schmizz.sshj.sftp.PacketReader.readPacket(PacketReader.java:76)
	at net.schmizz.sshj.sft
p.PacketReader.run(PacketReader.java:88)

With other sftp servers e.g. OpenSSH this doesn't happen. With 0.31.0 no error happens as well.

Attached a debug log of when this issue is reproduced
