[jira] Commented: (VFS-113) NullPointerException during getting
InputStream from SftpFileObject
[ https://issues.apache.org/jira/browse/VFS-113?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12482326 ]
Tim Rademacher commented on VFS-113:
------------------------------------
It's been a while since I wrote this. ;-) So by now, the only exception I get while trying to reproduce this was this IOException. As far as I remember, this has the same origin as the NullPointerException.
But I'll keep on trying to get you a stacktrace of the NullPointerException!
Regards,
Tim
