Validation of XML UTF-8 BOM file fails

[danielpeintner]

A simple code like the following with the attached XML file does not show the errors but struggles with the initial BOM and reports the error:

• Content is not allowed in prolog.

Set<String> set =  new XmlSchemaValidator().validateSchema(xml);

The UTF-8 BOM is a sequence of bytes at the start of a text stream (0xEF, 0xBB, 0xBF) that allows the reader to more reliably guess a file as being encoded in UTF-8.

Note: I had to zip the XML file being able to attach it to the issue.
