[ http://issues.apache.org/jira/browse/XALANJ-2134?page=all ]
Morris Kwan updated XALANJ-2134:
--------------------------------
Attachment: error_handling.patch
The file error_handling.patch contains a patch for error handling. Now the
default ErrorListener would not throw exceptions on errors. It also fixes a
conferr problem in XSLTC. And it includes a XSLTC workaround for the TCK
problem ErrorListener.errorTests.error001.
The test harness needs to be updated along with this change. The update will be
done in XALANJ-2139.
> JAXP 1.3: Fix error handling behavior
> -------------------------------------
>
> Key: XALANJ-2134
> URL: http://issues.apache.org/jira/browse/XALANJ-2134
> Project: XalanJ2
> Type: Bug
> Components: JAXP
> Versions: CurrentCVS
> Reporter: Morris Kwan
> Attachments: error_handling.patch
>
> Taken from the JAXP 1.3 javadocs on the javax.xml.transform package:
> The ErrorListener on both objects will always be valid and non-null, whether
> set by the application or a default implementation provided by the processor.
> The default implementation provided by the processor will report all warnings
> and errors to System.err and does not throw any Exceptions. Applications are
> strongly encouraged to register and use ErrorListeners that insure proper
> behavior for warnings and errors.
> The current ErrorListener implementations in Xalan interpretive and XSLTC do
> not completely conform to the spec. The default ErrorListener implementation
> in Xalan interpretive
> throws exceptions on errors and fatal errors. This causes a failure in the
> JAXP 1.3 TCK (testcase ErrorListener.error001). XSLTC also has its own
> problems on error handling. For example, it reports a warning by calling the
> ErrorListener.error() method.
> This is not something new in JAXP 1.3. I believe that JAXP 1.2 also has the
> same requirement. However, the JAXP 1.3 javadocs make it clearer that the
> default ErrorListener implementation should not throw exceptions.
