StackOverflowError for custom style with default name

[VolodymyrPashynskyi]

I received from client docx document where except default Normal style

    <w:style w:type="paragraph" w:default="1" w:styleId="Normal">
        <w:name w:val="Normal"/>
        <w:pPr>
            <w:spacing w:after="200" w:line="276" w:lineRule="auto"/>
            <w:ind w:left="0" w:right="0" w:firstLine="0"/>
        </w:pPr>
        <w:rPr>
            <w:rFonts w:ascii="Calibri" w:eastAsia="Calibri" w:hAnsi="Calibri" w:cs="Calibri"/>
            <w:sz w:val="22"/>
            <w:szCs w:val="22"/>
        </w:rPr>
    </w:style>

exist another style with the same name Normal that is based default one

    <w:style w:type="paragraph" w:styleId="Normal">
        <w:name w:val="Normal"/>
        <w:basedOn w:val="Normal"/>
        <w:next w:val="Normal"/>
        <w:pPr>
            <w:jc w:val="left"/>
            <w:ind w:left="0" w:right="0"/>
            <w:bidi w:val="false"/>
        </w:pPr>
        <w:rPr>
            <w:rFonts w:ascii="Arial" w:eastAsia="Arial" w:hAnsi="Arial" w:cs="Arial"/>
            <w:sz w:val="24"/>
            <w:szCs w:val="24"/>
        </w:rPr>
    </w:style>

It leads to StackOverflowError in PropertyResolver class on call fillPPrStack

I was not able to reproduce such document in Microsoft Word, but the original document is successfully openin

There are actually 2 problems here. The first is the duplicate styleId which you noticed.

The second (which leads to the StackOverflowError) is having a style based on itself:

    <w:style w:type="paragraph" w:styleId="Normal">
        <w:basedOn w:val="Normal"/>

Do you know how this docx was created?
