Description

Checkstyle wishes to upgrade our XML logger to print out XML 1.1 documents. We need this functionality to support escaping non-printable characters as XML 1.0 doesn't allow this and considers it an invalid document.
> Exception in thread "main" javax.xml.stream.XMLStreamException: ParseError at [row,col]:[45615,80]
> Message: An invalid XML character (Unicode: 0x2) was found in the value of attribute "message" and element is "error".

Checkstyle cannot upgrade until maven-checkstyle does as we use it in alot of regression testing. If we try to give the plugin an XML 1.1 document, it fails with the following error:
> [ERROR] Failed to execute goal org.apache.maven.plugins:maven-checkstyle-plugin:2.17:check (default-cli) on project postgresql: Unable to read Checkstyle results xml: /pipeline/source/pgjdbc/pgjdbc/target/checkstyle-result.xml: only 1.0 is supported as <?xml version not '1.1' (position: START_DOCUMENT seen <?xml version="1.1"... @1:19) -> [Help 1]
