Why ItemSkippedException?

Question

I am trying to update content in Google sites and am reading the stream in exception VersionConflictException.

When I check the stream it is all fine and is completely loaded in POST request but then I get following error.

Answer 1

FileItemStream.ItemSkippedException

This exception is thrown, if an attempt is made to read data from the InputStream, which has been returned by FileItemStream.openStream(), after Iterator.hasNext() has been invoked on the iterator, which created the FileItemStream.
