I caught NPE in case of parallel operations with files:
Caused by: java.lang.NullPointerException
	at org.apache.commons.vfs2.provider.sftp.SftpFileSystem.putChannel(SftpFileSystem.java:183)
	at org.apache.commons.vfs2.provider.sftp.SftpFileObject.doRename(SftpFileObject.java:215)

After short investigation I see issue in SftpFileSystem#getChannel
