將Java從1.8.0_45更新到1.8.0_131後，JAXB unmarshall字段爲空

我知道這與其他許多帖子是幾乎相同的，例如， JAXB doesn't unmarshall after updating java from 1.8.0_77 to 1.8.0_121 但這些答案或評論都沒有解決我的問題。將Java從1.8.0_45更新到1.8.0_131後，JAXB unmarshall字段爲空

（我也檢查了樣品這裏https://github.com/KlausGroenbaek/jaxbissue，並通過這個博客http://blog.bdoughan.com/2012/07/jaxb-no-annotations-required.html讀）

我升級我的Java 8，現在許多的使用示例XML文件測試失敗。

unmarshall返回一個所有字段都爲null的對象。

我不想要一個需要修改package-info或ObjectFactory的解決方案，因爲它們會自動重新生成並覆蓋所做的任何更改。

我聽說在其他地方，在POM Maven的選項

<strict>false</strict>

應該幫助，但它沒有。

我不確定它是否有相關差異，但我的schema xsd是在外部項目中定義的。

正如在原來的文章中，我也遇到了同樣的問題，而運行在不同的Java版本。 我添加了以下依賴項，並解決了我的問題

<dependency> 
     <groupId>org.jvnet.jaxb2.maven2</groupId> 
     <artifactId>maven-jaxb2-plugin</artifactId> 
     <version>0.13.3</version> 
    </dependency>
