--------------------------------------------------------------------- View the issue: http://issues.apache.org/jira/browse/XERCESJ-1015 Here is an overview of the issue: --------------------------------------------------------------------- Key: XERCESJ-1015 Summary: Zero byte read on InputStream causes false SAXParseException when LF at end of file Type: Bug Status: Unassigned Priority: Major Project: Xerces2-J Components: SAX Versions: 2.6.0 2.6.2 Assignee: Reporter: larry oneill Created: Fri, 1 Oct 2004 9:36 AM Updated: Fri, 1 Oct 2004 9:36 AM Environment: Windows XP, 586 Description: Under the following circumstances false SAXParseExceptions are thrown. When a document is being parsed and has reached the end of the document. If the InputStream supplying the document returns a 0 length indicator (meaning no bytes currently available) AND There is a Line Feed character at the end of the file, after the last element (without a carriage return). Then a false SAXParseException with one of the two following messages is thrown: "Content is not allowed in trailing section" or "The markup in the document following the root element must be well-formed" This could happen if the InputStream is reading from a buffer whose writer thread has returned a 0 instead of -1 when the buffer is closed. While the writer to the buffer should return a -1 on buffer close, in practice this may not always happen and Xerces should cater for it. It certainly should not throw a spurious exception. If a zero byte count is returned by an InputStream read while reading in the middle of the document an ArrayIndexOutOfBounds exception is thrown. I will include sample code to demonstrate both of these cases and a possible fix for the problem. --------------------------------------------------------------------- JIRA INFORMATION: This message is automatically generated by JIRA.
