[jira] [Created] (CAMEL-5423) NPE with Camel 2.10.0 and Bindy
Renato Weiner created CAMEL-5423:
------------------------------------
Summary: NPE with Camel 2.10.0 and Bindy
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:
from("direct:start").unmarshal().bindy(BindyType.Csv, "services.billing").to("direct:middle");
It works.
Expected result: if this the incorrect way to use, it should return a readable message.
Thanks.

[jira] [Commented] (CAMEL-5423) NPE with Camel 2.10.0 and Bindy

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()
