[jira] [Commented] (CXF-6375) Providers.getMessageBodyReader throws
NPE
[ https://issues.apache.org/jira/browse/CXF-6375?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14514194#comment-14514194 ]
Sergey Beryozkin commented on CXF-6375:
---------------------------------------
Passing a 'null' Type is a test issue, having a non-null Type is a basic expectation, but it is simpler to check for null rather than challenging this test.

> Key: CXF-6375
> URL: https://issues.apache.org/jira/browse/CXF-6375
> Project: CXF

> Environment: Windows

> Fix For: 3.1.0, 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.provider.AbstractJAXBProvider.objectFactoryForType(AbstractJAXBProvider.java:584)
> at org.apache.cxf.jaxrs.provider.AbstractJAXBProvider.isSupported(AbstractJAXBProvider.java:570)
> at org.apache.cxf.jaxrs.provider.AbstractJAXBProvider.isReadable(AbstractJAXBProvider.java:440)
> at org.apache.cxf.jaxrs.provider.ProviderFactory.chooseMessageReader(ProviderFactory.java:845)
> at org.apache.cxf.jaxrs.provider.ProviderFactory.createMessageBodyReader(ProviderFactory.java:504)
> 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.
