Alex Parvulescu commented on SLING-3114:
----------------------------------------
fyi. [~jukkaz] found out that this is triggered in the cases where the file
size is above 256000 bytes [0]
More on the failed import case:
It can be that the node name parameter passed in is not the same as the node
from system view export file.
For example I can export /content/page, and the name I pass in is
'jcr:content', and I ask to be imported under '/content'. this will affect how
the system view import verifies if the import was successful:
'content'.hasChild('jcr:content').
So I'm guessing that the importer could be a bit smarter about this check, as
failing it means another import will happen with a fallback on the default
importer.

> Key: SLING-3114
> URL: https://issues.apache.org/jira/browse/SLING-3114
> Project: Sling
> Issue Type: Bug
> Components: JCR
> Affects Versions: JCR ContentLoader 2.1.6
> Reporter: Alex Parvulescu
> Priority: Minor
> Fix For: JCR ContentLoader 2.1.8
>
>
> For the special case of system view imports the null check [0] fails to take
> into account the fact that the input stream is now closed (twice even [1],
> [2]).
> This means that if something happened and the import did not go throught
> (hence the _null_ node), the code will continue and fail later (line 99) with
> a cryptic message: _java.io.IOException: Stream Closed_ [3]
> My proposal (no patch) is to add an else clause with a warn log and a return
> statement.
