> Key: AXIS2-4661
> URL: https://issues.apache.org/jira/browse/AXIS2-4661
> Project: Axis2
> Issue Type: Bug
> Affects Versions: 1.5.1
> Reporter: Marco Tulio Valente
> Assignee: Afkham Azeez
> Priority: Minor
>
> Dear all,
> We are conducting an study about the relevance of the warnings reported by
> the FindBugs tool when executed over several open-source systems.
> Particularly, in the case of Axis2, we would like to confirm the relevance of
> the following warning reported by the tool (for Axis2 1.5.1):
> Warning: Invocation of toString on an array
> Locations:
> * org.apache.axis2.context.externalize.DebugObjectOutputStream write - Line
> 70
> * org.apache.axis2.jaxws.description.builder.ActionAnnot toString - Line 83
> * org.apache.axis2.jaxws.description.impl.AttachmentDescriptionImpl toString
> - Line 66
> * org.apache.axis2.jaxws.description.impl.OperationDescriptionImpl toString -
> Line 1559
> * org.apache.axis2.jaxws.message.util.Reader getTextCharacters - Line 277
> Warning: Nullcheck of value previously dereferenced. A value is checked here
> to see whether it is null, but this value can't be null because it was
> previously dereferenced and if it were null a null pointer exception would
> have occurred at the earlier dereference
> Location:
> * org.apache.axis2.jaxws.description.impl.URIResolverImpl constructPath -
> Line 284
> Warning: This call to a generic collection method contains an argument with
> an incompatible class from that of the collection's parameter (i.e., the type
> of the argument is neither a supertype nor a subtype of the corresponding
> generic type argument).
> Locations:
> * org.apache.axis2.jaxws.message.impl.MessageImpl getAttachmentID - Line 337
> * org.apache.axis2.jaxws.utility.XMLRootElementUtil
> createPropertyDescriptorMap - Line 209
> Warning: Null value is guaranteed to be dereferenced. There is a statement or
> branch that if executed guarantees that a value is null at this point, and
> that value that is guaranteed to be dereferenced
> Locations:
> * org.apache.axis2.schema.writer.CStructWriter process - Line 340
> * org.apache.axis2.schema.writer.JavaBeanWriter process - Line 489
> Warning: Null pointer dereference. A null pointer is dereferenced here.
> Location:
> * org.apache.axis2.saaj.SOAPHeaderImpl addUpgradeHeaderElement - Line 370
> Warning: Possible null pointer dereference. There is a branch of statement
> that, if executed, guarantees that a null value will be dereferenced, which
> would generate a NullPointerException
> Location:
> * org.apache.axis2.wsdl.codegen.emitter.AxisServiceBasedMultiLanguageEmitter
> getOutputParamElement - Line 3222
> Warning: Nullcheck of value previously dereferenced. A value is checked here
> to see whether it is null, but this value can't be null because it was
> previously dereferenced and if it were null a null pointer exception would
> have occurred at the earlier dereference.
> Location:
> * org.apache.axis2.wsdl.codegen.emitter.CEmitter addCSpecifcAttributes - Line
> 672
> Since these warnings seemed relevant to us, we would like to confirm our
> classification with Axis2's developers.
> Best regards,
