Talend Version (Required)	6.x
Summary	ESB Web Service call throws a NullPointerException when the web service takes a long time to send a reply.
Additional Versions
Product (Required)	ESB
Component (Required)	Web Services
Problem Description	Assume that a route is exposed as web service provider using a cCXF component, and that it also calls an external web service using another cCXF. If this external web service takes longer to respond, then the first cCXF throws a NullPointerException instead of a Timeout: java.lang.NullPointerException at org.apache.camel.impl.DefaultConsumer.doneUoW(DefaultConsumer.java:107)[158:org.apache.camel.camel-core:2.16.3] at org.apache.camel.component.cxf.CxfConsumer$1.asyncInvoke(CxfConsumer.java:112)[159:org.apache.camel.camel-cxf:2.16.3] at org.apache.camel.component.cxf.CxfConsumer$1.invoke(CxfConsumer.java:75)[159:org.apache.camel.camel-cxf:2.16.3] ...
Problem root cause	Camel issue
Solution or Workaround	Upgrade to Talend version 6.4.1. Also add the continuationTimeout argument in the first cCXF component ("Advanced settings"), and set it to a value greater than the ReceiveTimeout. For example, set it to 70000 (70 seconds) if you are using the default ReceiveTimeout of 60000 (60 seconds).
