Hello, I am getting a strange exception when trying to index some documents. The exception is as follows:

SEVERE: error while parsing the input file.

I run a command:

java -jar MIaS-1.6.6-4.10.4-SNAPSHOT.jar -conf ~/sandbox/mias/mias.properties -overwrite ~/sandbox/mias/data/samples/sample-mathml.xhtml ~/sandbox/mias/data/samples

My setup is:

MathMLCan: develop branch
MIaS: master branch
MIaSMath: master branch

$ java -version
java version "1.8.0_171"
Java(TM) SE Runtime Environment (build 1.8.0_171-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.171-b11, mixed mode)

The mias.properties configuration is:

INDEXDIR=~/sandbox/mias/indexes/index-0
UPDATE=false
THREADS=16
MAXRESULTS=10000
DOCLIMIT=-1
FORMULA_DOCUMENTS=true

The sample-mathml.xhtml file is as simple as:

<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml">
  <head>
    <meta http-equiv="Content-Type" content="application/xhtml+xml; charset=UTF-8" />

          <mi> x </mi>
          <mo> + </mo>
          <mi mathcolor="red"> y </mi>
          <mo> + </mo>

        </mrow>
      </mfrac>
      <mfenced open=":" close="?">
      </mfenced>
    </math>
  </body>
</html>

Is there please any help out there or any ideas what could be a problem here?
