Subject [jira] [Commented] (VFS-200) sftp fails when files are very large
Date Mon, 14 May 2012 18:31:54 GMT

    [ https://issues.apache.org/jira/browse/VFS-200?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13274829#comment-13274829
] 

Gary D. Gregory commented on VFS-200:
-------------------------------------

Yes, this was addressed by [VFS-410][SFTP]: SftpFileObject getInputStream(long) reads the
whole file into memory.

It is in SVN as of revision 1328346.
