Exceptions on resizing - Githubissues

Hi @Dansoftowner
When I resize my application's window with a PDF loaded via PDFViewerFX, often (not always) I find the following Exception:
myMac2014:target stephan$ java -jar document-archiver-1.6.0-SNAPSHOT-with-dependencies.jar 
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

I am also using WebViews with other file types and there I don't see any problem. So I would guess it's not my application code. Tried to go back to version 0.7, just to find the problem exists there, too.
Any ideas?
Thanks and best regards Stephan
