Claus Ibsen resolved CAMEL-1788.
--------------------------------

    Resolution: Incomplete

Closing this as reported is providing details and the problem is the flatpack library and
not Camel

>                 Key: CAMEL-1788
>                 URL: https://issues.apache.org/activemq/browse/CAMEL-1788
>             Project: Apache Camel
>          Issue Type: Bug
>          Components: camel-flatpack
>    Affects Versions: 1.6.0
>         Environment: Flatpack 3.1.1
> Fuse ESB 4.1.0.0 (Apache Servicemix)
> Camel 1.6.0.0-fuse
>            Reporter: Scott Parkerson
>            Assignee: Willem Jiang
>
> The following code will not work under Servicemix, but works fine in standalone Camel:
> {code:java}
>         FlatpackDataFormat fpdf = new FlatpackDataFormat();
>         fpdf.setDefinition(new ClassPathResource("dataspecs/mypzmap.xml"));
>         fpdf.setFixed(false);
>         fpdf.setDelimiter('|');
>         fpdf.setIgnoreFirstRecord(false);
>         from("activemq:" + incomingQueueName).convertBodyTo(String.class).unmarshal(fpdf).to("activemq:input_to_call");
> {code}
> This NPEs when attempting to unmarshal under SMX 4, but works fine in Camel 1.6.x. I've
traced down the problem to this code in Flatpack: 
> {code:title=net/sf/flatpack/util/ParseUtils.java}
>     public static Properties loadConvertProperties() throws IOException {
>         final Properties pzConvertProps = new Properties();
>         final URL url = ParserUtils.class.getClassLoader().getResource("fpconvert.properties");
>         pzConvertProps.load(url.openStream());
>         return pzConvertProps;
>     }
> {code}
> The classloader under SMX is the bundle's classloader, which (of course) cannot find
fpconvert.properties, which makes url null, and then causes pzConvertProps.load(...) to raise
an NPE.
> I know that this isn't strictly a bug in Camel or SMX, but I thought I'd file it here
as an action item to either change upstream flatpack or note a possible workaround on the
wiki.
> I suspect that this is a problem with all versions of Camel + SMX including the latest
version.
