Description

Steps to produce: 

• Create an empty adoc file in any component.
• Run camel-package:update-readme.
• It will fail with the following error:

  Caused by: java.lang.ArrayIndexOutOfBoundsException: Index 1 out of bounds for length 1

      at org.apache.camel.maven.packaging.UpdateReadmeMojo.execute (UpdateReadmeMojo.java:105)
  

• As I can see here, it looks it will try to retrieve index although there are empty lines
