Xerces builds - Why don't they include line number attributes?
Hello,
Is it possible that when building Xerces builds for Java in the future,
you could turn the line number attributes on? It makes it easier for
developers to set breakpoints and trace through code. Currently, any
Java stack traces involving xerces look something like this (with line
number information not available):
org.apache.xerces.impl.xs.XMLSchemaLoader.loadGrammar(XMLInputSource[])
line: not available
org.apache.xerces.jaxp.validation.XMLSchemaFactory.newSchema(Source[])
line: not available
org.springframework.xml.validation.SchemaLoaderUtils.loadSchema(Resource
[], String) line: 73
org.springframework.xml.validation.Jaxp13ValidatorFactory.createValidato
r(Resource[], String) line: 40
You can see that the SpringFramework JARs include line numbers, making
their code easier to trace; the Xerces JARs do not, which means we can
only see the class/method names. The last time I built Xerces, I
remember this behavior was already integrated into the Xerces build, but
was disabled by default. Not sure if this is by design or simply an
oversight. Maybe it should be enabled by default, or maybe whatever
process or person builds these final releases could be updated/educated
to include this flag?
Thanks,
- Aaron

My mistake, thanks for your patience.

Aaron,
You picked the wrong mailing list. c-users@ is for Xerces-C. I'm sure
you
meant to post this to the Java users list.
Also, please see previous discussion on this topic in the archives [1].
Thanks.
