Occasional NullPointerException

[madflow]

I haven't found a way to reproduce this yet. Maybe this is just on a linux machine..

The NPE occurs when previewing a .md file.

Tested with this commit:

Did you find a work around?

I have not - I could not reproduce it. To me it seemed like a random error, which could be caused by a timeout when rendering a document. Pretty vague.

Can you reproduce this every time you try to render a certain document?

Seems to be a javafx upstream bug https://javafx-jira.kenai.com/browse/RT-37862
