Charles Moulliard commented on CAMEL-5423:
------------------------------------------
Where do you deploy your camel project (JBoss, WebSphere, Tomcat, ...)?
According to camel-bindy code, the NPE is generated when we try to get the
package and name from the type. As the type object is not null, this is the
package object which should be null.
public void initModel() throws Exception {
// Find classes defined as Model
if (packageNames != null) {
initModelClasses(this.packageNames);
} else if (type != null) {
// use the package name from the type as it may refer to types in
the same package
String pckName = type.getPackage().getName(); // NPE generated here
According to Java Doc, the package could be null if no package object was
created by the class loader of this class
http://docs.oracle.com/javase/6/docs/api/java/lang/Class.html#getPackage()

> Key: CAMEL-5423
> URL: https://issues.apache.org/jira/browse/CAMEL-5423
> Project: Camel
> Issue Type: Bug
> Components: camel-bindy
> Affects Versions: 2.10.0
> Environment: Windows 7, Java 1.6.0_31
> Reporter: Renato Weiner
> Priority: Minor
>
> Running this route:
> from("direct:start").unmarshal().bindy(BindyType.Csv,
> services.billing.BillingItem.class).to("direct:middle");
> Where services.billing.BillingItem.class exists and has the following
> annotations:
> @CsvRecord(separator = ",", quote = "\"", skipFirstLine = true)
> public class BillingItem {
> ...
> It throws a NPE:
> java.lang.NullPointerException

> When I change the code to:

> "services.billing").to("direct:middle");
> It works.
> Expected result: if this the incorrect way to use, it should return a
> readable message.
> Thanks.
