----------------------------
Summary: Providers.getMessageBodyReader throws NPE
Key: CXF-6375
URL: https://issues.apache.org/jira/browse/CXF-6375
Project: CXF
Issue Type: Bug
Components: JAX-RS
Affects Versions: 3.0.3
Environment: Windows
Reporter: Neal Hu
Fix For: 3.0.5
org.apache.cxf.jaxrs.impl.ProvidersImpl.getMessageBodyReader and
org.apache.cxf.jaxrs.impl.ProvidersImpl.getMessageBodyWriter are public methods
that can be invoke by end user via injected
providers.getMessageBodyReader(x,null,x,x).
Recently we received TCK failure(NPE) on invoke above method when the Type
genericType is null.
the stack trace is:
at java.lang.Class.isAssignableFrom(Native Method)
at
org.apache.cxf.jaxrs.provider.JAXBElementProvider.objectFactoryOrIndexAvailable(JAXBElementProvider.java:109)

at
org.apache.cxf.jaxrs.impl.ProvidersImpl.getMessageBodyReader(ProvidersImpl.java:45)
How do you think the value of genericType is null? Is it valid or not. If not
we may challenge the TCK case. However the NPE is not allowed.
