Java.swl.x.

我有一个UTF-16 XML文件：

<?xml version="1.0" encoding="utf-16" standalone="yes"?>

它从BOM FE FF开始。

将我的代码迁移到Java 11，我得到：

Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,1]
Message: Content is not allowed in prolog.
    at com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.next(XMLStreamReaderImpl.java:652) ~[?:?]

这是使用JAXB解组它。

我是否使用参考实现会发生这种情况：

Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[1,1]
Message: Content is not allowed in prolog.
    at com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.next(XMLStreamReaderImpl.java:652) ~[?:?]
    at com.sun.xml.bind.v2.runtime.unmarshaller.StAXStreamConnector.bridge(StAXStreamConnector.java:134) ~[jaxb-runtime-2.4.0-SNAPSHOT.jar:?]
    at com.sun.xml.bind.v2.runtime.unmarshaller.UnmarshallerImpl.unmarshal0(UnmarshallerImpl.java:385) ~[jaxb-runtime-2.4.0-SNAPSHOT.jar:?]
    at com.sun.xml.bind.v2.runtime.unmarshaller.UnmarshallerImpl.unmarshal(UnmarshallerImpl.java:356) ~[jaxb-runtime-2.4.0-SNAPSHOT.jar:?]

或者MOXy：

Message: Content is not allowed in prolog.
    at com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl.next(XMLStreamReaderImpl.java:652) ~[?:?]
    at org.eclipse.persistence.internal.oxm.record.XMLStreamReaderReader.parse(XMLStreamReaderReader.java:98) ~[org.eclipse.persistence.core-2.5.2.jar:?]
    at org.eclipse.persistence.internal.oxm.record.XMLStreamReaderReader.parse(XMLStreamReaderReader.java:86) ~[org.eclipse.persistence.core-2.5.2.jar:?]
    at org.eclipse.persistence.internal.oxm.record.SAXUnmarshaller.unmarshal(SAXUnmarshaller.java:895) ~[org.eclipse.persistence.core-2.5.2.jar:?]
    at org.eclipse.persistence.oxm.XMLUnmarshaller.unmarshal(XMLUnmarshaller.java:659) ~[org.eclipse.persistence.core-2.5.2.jar:?]
    at org.eclipse.persistence.jaxb.JAXBUnmarshaller.unmarshal(JAXBUnmarshaller.java:585) ~[org.eclipse.persistence.moxy-2.5.2.jar:?]

它们都使用com.sun.org.apache.xerces.internal.impl.XMLStreamReaderImpl

使用Java 6到8解组该文件工作正常。在Java 9或11中有什么变化吗？

如果我删除了FE FF BOM，它将使用Java 11解组。

答案

原来我的问题是由maven-resources-plugin引起的，过滤设置为true。这会破坏任何UTF-16资源，将前2个字节更改为EF BF。
