[jira] [Commented] (XALANJ-2419) Astral characters written as a pair of NCRs with the surrogate scalar values when using UTF-8
[ https://issues.apache.org/jira/browse/XALANJ-2419?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=18058573#comment-18058573 ]
Ilya Basin commented on XALANJ-2419:
------------------------------------
Apparently version 2.7.3 on Maven Central was built from the git tag xalan-j_2_7_3-rc10. I built this tag locally with the openjdk8, it printed warnings like "ClassNotFoundException: com.sun.image.codec.jpeg.JPEGCodec", but the jars were built. I compared the class files, they're identical. The fixing commit 9e67d121c547dc82157b7852fd7b23eb9f260071 also merges smoothly and my XMLs are now good.
To bump the version to 2.7.3.1 I had to edit build.xml:
{code:java}
- <property name="version" value="${version.VERSION}_${version.RELEASE}_${version.DEVELOPER}${version.MINOR}"/><!-- GUMP: version # of dist file -->
- <property name="impl.version" value="${version.VERSION}.${version.RELEASE}.${version.DEVELOPER}${version.MINOR}"/><!-- Used in jar task for filtering MANIFEST.MF file -->
+ <property name="version.MINOR2" value=".1"/>
+ <property name="version" value="${version.VERSION}_${version.RELEASE}_${version.DEVELOPER}${version.MINOR}${version.MINOR2}"/><!-- GUMP: version # of dist file -->
+ <property name="impl.version" value="${version.VERSION}.${version.RELEASE}.${version.DEVELOPER}${version.MINOR}${version.MINOR2}"/><!-- Used in jar task for filtering MANIFEST.MF file --> {code}

> Key: XALANJ-2419
> URL: https://issues.apache.org/jira/browse/XALANJ-2419
> Project: XalanJ2
> Issue Type: Bug
> Components: Serialization
> Affects Versions: 2.7.1
> Reporter: Henri Sivonen
> Assignee: Joe Kesselman
> Priority: Major
> Fix For: The Latest Development Code
>
> Attachments: XALANJ-2419-fix-v3.txt, XALANJ-2419-tests-v3.txt
>
>
> org.apache.xml.serializer.ToStream contains the following code:
> else if (m_encodingInfo.isInEncoding(ch)) {
> // If the character is in the encoding, and
> // not in the normal ASCII range, we also
> // just leave it get added on to the clean characters
>
> }
> else {
> // This is a fallback plan, we should never get here
> // but if the character wasn't previously handled
> // (i.e. isn't in the encoding, etc.) then what
> // should we do? We choose to write out an entity
> writeOutCleanChars(chars, i, lastDirtyCharProcessed);
> writer.write("&#");
> writer.write(Integer.toString(ch));
> writer.write(';');
> lastDirtyCharProcessed = i;
> }
> This leads to the wrong (latter) if branch running for surrogates, because isInEncoding() for UTF-8 returns false for surrogates. It is always wrong (regardless of encoding) to escape a surrogate as an NCR.
> The practical effect of this bug is that any document with astral characters in it ends up in an ill-formed serialization and does not parse back using an XML parser.
