Joe Kesselman commented on XALANJ-2422:
---------------------------------------
*WARNING:* TreeWalker exists in both org.apache.xml.serializer and
org.apache.xml.utils, with some divergence, This was originally done to avoid
cross-dependency between the serializer and utils. We should think about
reconciling those.
It appears this user was looking at the .utils version. The logic does diverge
a bit in this function. I'm too fuzzy to reconcile them right now but wanted to
record this much.

> Key: XALANJ-2422
> URL: https://issues.apache.org/jira/browse/XALANJ-2422
> Project: XalanJ2
> Issue Type: Bug
> Components: Xalan
> Affects Versions: 2.7.1, 2.7
> Reporter: Brian McDonald
> Priority: Blocker
> Attachments: TreeWalker.patch
>
>
> If you take a look at the merge of the TreeWalker.patch
> (org/apache/xml/serializer/TreeWalker.java) between versions 338117 and
> 338053 (for XALANJ-1985), the constructor has some remnant code at the end
> which breaks it's intended functionality.
> This chunk should be removed (sorry for not attaching a patch):
> // Set the document locator
> if (m_contentHandler != null)
> m_contentHandler.setDocumentLocator(m_locator);
> try {
> // Bug see Bugzilla 26741
> m_locator.setSystemId(System.getProperty("user.dir") +
> File.separator + "dummy.xsl");
> }
> catch (SecurityException se){// user.dir not accessible from
> applet
> You can see that the constructor before this chunk already sets the document
> locator on the content handler and if the system id is null, sets the dummy
> value. Problem is that this extra chunk is setting the system id no matter
> what, which breaks all attempts to load relative files, with no workaround
> possible.
