About a month ago, I had to disable jai-ext, because it was making blank tiles 
randomly for some of my imagemosaic layers.

Subject: Problem with imagemosaic when zoomed in beyond 1 : 2M


Actually there are two (probably related) problems.

  1.   When zoomed into a layer in EPSG:3857 to 1:2M scale, a portion of the 
image will be missing, usually at the bottom.  When I zoom out, it fills in.
  2.  When zoomed into a layer in EPSG:3857 to a higher resolution than 1:2M, I 
get this error in the results from GetMap:  Error rendering coverage on the 
fast path.  All factories fail for the operation "and"The intersection of all 
the source bounds is empty

    I'm using geoserver 2.16.2 on linux.  The layer has a resolution of 0.125 x 
0.125 degrees, and is in EPSG:4326, covering the whole Earth.  There are two 
different styles I have for this layer.  One that works draws line contours at 
specific values using the ras:Contour transformation.

The one that fails is this one:
