title: Liquibase cannot find parser
body: <p>I am getting a Liquibase exception when running update.  </p>
  
  <pre><code>Caused by: liquibase.exception.UnknownChangelogFormatException: 
  Cannot find parser that supports &lt;?xml version="1.0" encoding="UTF-8" standalone="no"?&gt;
  </code></pre>
  
  <p>I thought Liquibase by default supports xml parsing so I am not sure of the case here.  Am I missing a configuration when I initialize the class?</p>
  
  <pre><code>  private lazy val liquibase: Liquibase = {
      val fsFO: ResourceAccessor = new FileSystemResourceAccessor
      val clFO: ResourceAccessor = new ClassLoaderResourceAccessor
      val contextClassLoader = Thread.currentThread().getContextClassLoader
      val threadClFO: ResourceAccessor = new ClassLoaderResourceAccessor(contextClassLoader)
      val database = DatabaseFactory.getInstance.findCorrectDatabaseImplementation(new JdbcConnection(connection))
      new Liquibase(changeLog, new CompositeResourceAccessor(clFO, fsFO, threadClFO), database)
    }
  
    def update(): Unit = Try(liquibase.update(context)) match {
      case Success(_) =&gt; log.info("LIQUIBASE FINISHED: Update change log")
      case Failure(ex) =&gt; throw new Exception("LIQUIBASE FAILED: Update change log", ex)
    }
  </code></pre>
  
  <p>The variable <strong>changelog</strong> is the <em>String</em> read using `java.o.File</p>
  
  <pre><code>  val fileReader = new FileReader(file)
    val characters = new Array[Char](file.length().toInt)
    fileReader.read(characters)
    new String(characters)
  </code></pre>
  
  <p>Master.xml</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="no"?&gt;
