Description

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)
at org.apache.commons.vfs2.provider.AbstractFileObject.moveTo(AbstractFileObject.java:1668)

After short investigation I see issue in SftpFileSystem#getChannel
