> 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 Xerces, we would like to confirm the relevance of the following warnings reported by the tool (for Xerces
> 2.8.1):
> Location: org.apache.xerces.impl.xpath.regex.RangeToken dumpRanges - Line 481
> Warning: Possible null pointer dereference. There is a branch of statement that, if executed, guarantees that a null value will be dereferenced
> Location: org.apache.xerces.impl.xpath.regex.RangeToken intersectRanges - Line 351
> Warning: Self comparison of value with itself. This method compares a local variable with itself, and may indicate a typo or a logic error.
> Location: org.apache.xerces.util.DOMUtil copyInto - Line 119
> Warning: Null pointer dereference. A null pointer is dereferenced here.  This will lead to a NullPointerException when the code is executed.
> Location: org.apache.xerces.xinclude.XIncludeTextReader getReader - Line 181
> 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
> Since these warnings seemed relevant to us, we would like to confirm our classification with Xerces's developers.
> Best regards,
> Marco Tulio Valente
