解決：

• 方法一 flowable-engine/modules/flowable-dmn-xml-converter/src/main/resources/org/flowable/impl/dmn/parser/dmn.xsd <xsd:schema xmlns="http://www.omg.org/spec/DMN/20151101" ... 修改成 <xsd:schema xmlns="http://www.omg.org/spec/DMN/20151101/dmn.xsd" ...

• 方法二 org.flowable.dmn.xml.constants.DmnXMLConstants public static final String DMN_NAMESPACE = "http://www.omg.org/spec/DMN/20151101"; 修改成 public static final String DMN_NAMESPACE = "http://www.omg.org/spec/DMN/20151101/dmn.xsd"; 或者DMN1.2的xsd

官方在6.5.0版本已修復該bug。 詳見issues flowable#255，和pull requests flowable#1700
