Hi all,
Running Geoserver 2.8 and have an imagemosaic store with a NetCDF. The NetCDF 
defines a grid which crosses the dateline (x range [150,240], equivalent to 
150E to 120W, or 150 to -120). The NetCDF is stored in EPSG:4326.

Through WMS, if I request the data with a minX/maxX of 0,360 the grid is drawn 
correctly in the middle of the image.
However, if I specify a minX/maxX of -180,180, only part of the grid is drawn 
on the right side of the image (the section between 150,180). The section 
between 180,240, or -180,-120, expected on the left side of the image, is not 
drawn.

I assume this is caused by the NetCDF reader not wrapping the dateline 
correctly. For example, x=190 is not mapped to -170, so no data is found.

Is there a workaround to this issue?

Again, this issue is only seen on grids which cross the dateline.

Thanks,
-ap
