I have the following XML:

<?xml version="1.0" encoding="UTF-8"?>
<details>
  ...
  <address1>Test&amp;Address</address1>
  ...
</details>

When I try to unmarshal it using JAXB, it throws the following exception:

Caused by: org.xml.sax.SAXParseException: The reference to entity "Address" must end with the ';' delimiter.

But when I changed the & in the XML to ', it works. Looks like the problem is only with ampersand & and I cannot understand why.

The code to unmarshal is:

JAXBContext context = JAXBContext.newInstance("some.package.name", this.getClass().getClassLoader());
Unmarshaller unmarshaller = context.createUnmarshaller();
obj = unmarshaller.unmarshal(new StringReader(xml));

Anyone have some insight?
