[jira] Created: (XERCESJ-1169) With XMLGrammarCachingConfiguration, some Text nodes are completely missing from the DOM.

With XMLGrammarCachingConfiguration, some Text nodes are completely missing from the DOM.
-----------------------------------------------------------------------------------------

         Key: XERCESJ-1169
         URL: http://issues.apache.org/jira/browse/XERCESJ-1169
     Project: Xerces2-J
        Type: Bug

    Versions: 2.8.0    
 Environment: Java-1.4.2_09, Eclipse_3.2RC7, JUnit, tests parsing complex document with embedded XML DSIG using namespaces.
    Reporter: Tom Oehser


I am parsing a document which has an XML DSIG signature, when I turn on System.setProperty( "org.apache.xerces.xni.parser.XMLParserConfiguration",             "org.apache.xerces.parsers.XMLGrammarCachingConfiguration"); sometimes (I think the first time is fine, the second time and higher it fails) the "SignatureValue" Element node has child Text node.  Parsing without the Caching configuration is find, there is always a Text node under the SignatureValue Element node.  Parsing with the CachingConfiguration, the first time it has a Text child node, the next time and thereafter, there is no child of the SignatureValue node at all.

-----------------------------------------------

Sounds like the GUMP builds these days are being done with Java 5.0. You could verify that by reading the manifest file in xercesImpl.jar.  If you need to build on an earlier JDK you can do that yourself if you extract the source from SVN. It's located here: http://svn.apache.org/repos/asf/xerces/java/trunk/.

-------------------------------------

Note, the zip file should be unzipped in a src/ directory, it will create a package, which includes DTDs etc. that are needed by the test.  There is one .java and one .xml file, the .java has a simple entity resolver to pull the DTDs with the classloader from the same package.  It should be fairly easy to reproduce it... -Tom

-----------------------------------------------

Xerces' caching of DTD grammars has its limitations (particuarly with respect to internal subsets [1]) but this definitely a bug.  The endDTD() event isn't being fired at the DOM builder.  This causes it to drop *all* of the text in the document.  I'll see if I can fix it.

Ok, here is a test that reproduces it.  It might have something to do with the document having an internal subset.  The test shows that with default configuration, it just works, with the grammer caching, it works once, then fails. -Tom

Michael,
I have this same issue, but when I replace the 2.8.0 xercesImpl.jar with the latest from GUMP, I get a java.lang.UnsupportedClassVersionError: org/apache/xerces/jaxp/DocumentBuilderFactoryImpl (Unsupported major.minor version 49.0).  I'm running jdk1.4.2_05.  What do I need to do to be able to use Xerces with this fix?  Can I get the latest source and build it myself?
Thanks,
-Kit
