Hi Jorge,
I think, this error is not specific to XSD assertions. Setting a
error handler on the JAXP validator object would solve this problem.
Following are the proposed changes to solve this issue,
Validator v = s.newValidator();
v.setErrorHandler(new ErrHandler());
v.validate(new StreamSource(instance));
and define a suitable error handler as following,
class ErrHandler implements ErrorHandler {
...
}
