> camel-stream - stream:file with a file name without a directory, and
> stream:header without the stream header, fail with a NullPointerException

> Key: CAMEL-25974
> URL: https://issues.apache.org/jira/browse/CAMEL-25974
> Project: Camel
> Issue Type: Bug
> Components: camel-stream
> Affects Versions: 4.18.0, 4.22.0, 4.23.0
> Reporter: Claus Ibsen
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 4.24.0
>
>
> Two producers of camel-stream fail with a NullPointerException instead of an
> error that says what is wrong:
> * {{stream:file?fileName=out.txt}}, a file name without a directory:
> {{f.getParentFile().mkdirs()}} ({{StreamProducer}}, main e6885df7894d, line
> 100) fails because the parent is null;
> * {{stream:header}} without a {{stream}} header, or with one that is not an
> OutputStream: the stream is null, and the {{OutputStreamWriter}} at line 141
> fails.
> Checked on 4.24.0-SNAPSHOT with {{camel run}}:
> * {{NullPointerException: Cannot invoke "java.io.File.mkdirs()" because the
> return value of "java.io.File.getParentFile()" is null}};
> * {{NullPointerException}} from {{java.io.Writer.<init>}}.
> *Proposed change*: create the parent directories only when there is a parent,
> and fail with a clear error when the stream header is missing.
