---------------------------------------------

[~tilman] I switched jobs last year and no longer work with PDFBox. Kudos on fixing the issue
though :)

> Annotations containing "&" in their text are displayed incorrectly when parsed unmodified
from XFDF (the ampersands are encoded as "&amp;" there) and added to a PDF document.
>  This occurs for both "text comment" and "text box" type annotations.
>  However, if the XFDF is modified by replacing "&amp;" with "&amp;amp;" prior
to parsing, the imported annotations are then displayed correctly.
> The attached code produces two pdf files. One is the PDF with the unmodified XFDF imported,
two the PDF with the modifed XFDF.
> A XFDF containing both a text box and text comment annotation is embedded in the source
and attached as a separated file.
> Update 23.03.2017 : This problem persists in 2.0.5 and we noticed the same corruption
of merged annotations occur, if the annotation text contains a "<" (encoded as "lt" entity)
> Update 17.10.2018 : This corruption is caused by FDFAnnotation.richContentsToString.
This method reads "<" and "&" from the parsed values in the document and puts them
as such into the markup, but these characters must be replaced with their entities.
> I'll add this substitution to my proposed bugfix of 4345, please refer to https://issues.apache.org/jira/projects/PDFBOX/issues/PDFBOX-4345
