Tobias Bocanegra commented on JCRVLT-349:
-----------------------------------------
I agree, that it would be better to have a consistent behaviour. I don't agree
with 2), as the input stream is always fully consumed (at lest in filevault). a
caller would need to create a limiting sub-stream.
I wouldn't change the behaviour as it is right now, but to eliminate
inconsistencies within method calls, and update the javadoc.
[~kwin] Do you have a concrete use case where this is a problem?

> URL: https://issues.apache.org/jira/browse/JCRVLT-349
> Project: Jackrabbit FileVault
> Issue Type: Wish
> Components: vlt
> Affects Versions: 3.2.8
> Reporter: Konrad Windszus
> Priority: Major
>
> There are several places in the FileVault code where an input stream is
> passed as argument to a method and closed within it (even though this is not
> explicitly mentioned in the javadocs). I think this is bad for the following
> reasons:
> # it is unexpected for the caller that the given input stream is closed (i.e.
> this is also never the case for methods taking an input stream in
> {{org.apache.commons.io.IOUtils}} nor in the JRE itself
> (https://docs.oracle.com/javase/7/docs/api/java/util/Properties.html#load(java.io.InputStream)))
> # closing the input stream might actually have an undesired effect if the
> input stream may contain additional input which is supposed to be consumed
> afterwards
> # closing often happens in a way that there may be leaks in case of
> exceptions.
> # the behaviour is not documented
> Examples for such behaviour are at

> If I am not incorrect the behaviour is also not consistent as e.g. in
> https://github.com/apache/jackrabbit-filevault/blob/6df76ba4a45316a84ec1cd10636296d191a82260/vault-core/src/main/java/org/apache/jackrabbit/vault/fs/config/DefaultMetaInf.java#L136
> the input stream is not closed.
