[jboss-jira] [JBoss JIRA] Commented: (AS7-1231) Horrible XML parsing error reports

[Jason Greene (JIRA)]

    [ https://issues.jboss.org/browse/AS7-1231?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12613468#comment-12613468 ] 

Jason Greene commented on AS7-1231:
-----------------------------------

BTW staxmapper doesn't do anything special like I for some reason thought it did.

The problem is caused when someone does something like this <thing></thing>@#@#%$@$WEF<other></other>. So the error message is actually accurate, it's just obtuse. It could be a bit more human friend/verbose if we implemented something like I thought we did in staxmapper (but do not) where we implement a nextTag which explains what in more detail what went wrong. See

http://download.oracle.com/javase/6/docs/api/javax/xml/stream/XMLStreamReader.html#nextTag()

I like the idea of putting location early.
