Michael Glavassevich resolved XERCESJ-1431.
-------------------------------------------
Resolution: Not A Problem
Perhaps it should be cleaned up at some point, but it's not high on the
priority list. Since it isn't used it isn't hurting anyone today. Consider that
most of the developers have limited time to work on the project. For what
little time I have I'd rather spend it on making visible improvements for
users, not browsing through the code looking for dead methods to delete.
If you have further questions please ask them on the mailing list. The bug
database is not meant for this kind of discussion.

> Key: XERCESJ-1431
> URL: https://issues.apache.org/jira/browse/XERCESJ-1431
> Project: Xerces2-J
> Issue Type: Bug
> Components: Other
> Affects Versions: 2.8.1
> Reporter: Marco Tulio Valente
>
> 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.
