Unable to allocate direct buffer memory

[John Hendrikx]

They're related.  32767x1137x4 = 149024316.

It would help to know what your app might be doing.  Although it could 
be a bug in JavaFX, it seems more likely that a canvas/image or cached 
group or something is a bit bigger than reasonable.

I think I've seen such errors in my app before I restricted maximum 
sizes of images which were supplied from uncontrolled sources.
