Single words conduct to have a wrong POS which leads to a crash of the target feature module

[seblemaguer]

Considering the text "Mace", at the PARTOFSPEECH stage you achieve this XML

<?xml version="1.0" encoding="UTF-8"?><maryxml xmlns="http://mary.dfki.de/2002/MaryXML" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="0.5" xml:lang="en-US">
<p>
<s>
<t pos="NNP">
Mace
</t>
<t pos=".">
.
</t>
</s>
</p>
</maryxml>

problem is the pos attribute="." which apparently cause this error

java.lang.Exception: Module TargetFeatureLister: Problem processing the data.
