Michael Glavassevich resolved XERCESJ-1495.
-------------------------------------------
Resolution: Invalid
This is not a bug.
You are assuming that all character data of an element is reported in a single
chunk. This is probably the most common SAX programming error.
characters() may be called multiple times (please review the SAX API Javadoc
and FAQs here [1] and here [2]) for contiguous text. Your ContentHandler needs
to accumulate the text returned in each call of characters() until you receive
a callback that isn't characters.
Thanks.

> Hi
> I see following problem after upgrading from Xerces1 to Xerces2
> Xerces2 misbehaves if the value includes "]" character.
> Here is an example for old (Xerces1) and new (Xerces2) behaviour the given
> xml chunk. ( Problem not exist for CDATA fields )
> I believe same problem (logically) was reported for Xerces C++ before
> (https://issues.apache.org/jira/browse/XERCESC-1226?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#issue-tabs
