poi 3.9 报错：

原因是一样的：
通过调式定位，poi 类的源码不严谨造成；

package org.apache.poi.xwpf.converter.core.styles.run;import org.apache.poi.xwpf.converter.core.styles.XWPFStylesDocument;
import org.apache.poi.xwpf.usermodel.UnderlinePatterns;
import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTRPr;public class RunUnderlineValueProvider extends AbstractRunValueProvider<UnderlinePatterns>{public static final RunUnderlineValueProvider INSTANCE = new RunUnderlineValueProvider();@Overridepublic UnderlinePatterns getValue( CTRPr rPr, XWPFStylesDocument stylesDocument){return ( rPr != null && rPr.isSetU() ) ? UnderlinePatterns.valueOf( rPr.getU().getVal().intValue() ): null;}
}

public class RunUnderlineValueProvider extends AbstractRunValueProvider<UnderlinePatterns>{public static final RunUnderlineValueProvider INSTANCE = new RunUnderlineValueProvider();@Overridepublic UnderlinePatterns getValue( CTRPr rPr, XWPFStylesDocument stylesDocument){// 注意返回时rPr.getU()!=null && rPr.getU().getVal()!=null 判空return ( rPr != null && rPr.isSetU() && rPr.getU()!=null && rPr.getU().getVal()!=null) ? UnderlinePatterns.valueOf( rPr.getU().getVal().intValue() ): null;}
}

这样就会覆盖掉源码（优先调用）

最终解决的办法是修改jar包版本，一定要对应上。
