Hi all,
I have a unit test in place which fires checks critical pixels of a
transformed GridCoverage. The wired constellation is that the code works
when the test runs standalone: "gradle -Dtest.single=ReprojectionTest test"
but will fail when it is part of the full test run "gradle test"
The projection itself is straight forward:
GridCoverage2D transformedCoverage = (GridCoverage2D)
Operations.DEFAULT.resample(coverage, targetCrs)
Trying to extract the BufferedImage out of it is throwing a
NullPointerException (see stack below). Here's the code:
BufferedImage bi =
((PlanarImage)transformedCoverage.getRenderedImage()).getAsBufferedImage();
And here is the NPE:
java.lang.NullPointerException
at com.sun.media.jai.util.SunCachedTile.<init>(SunCachedTile.java:80)
at com.sun.media.jai.util.SunTileCache.add(SunTileCache.java:257)
at javax.media.jai.OpImage.addTileToCache(OpImage.java:1087)
at javax.media.jai.OpImage.getTile(OpImage.java:1142)
at javax.media.jai.PlanarImage.copyData(PlanarImage.java:2343)
at javax.media.jai.RenderedOp.copyData(RenderedOp.java:2299)
at javax.media.jai.PlanarImage.getAsBufferedImage(PlanarImage.java:2525)
at javax.media.jai.PlanarImage.getAsBufferedImage(PlanarImage.java:2546)
Again: everything works fine when the test runs standalone but will throw
that exception in global context.
Thanks and best regards,
tee
