ImageMosaicReaderTest is failing on a Windows machine
This line in the test will fail on Windows machines:
new GeoTiffWriter(new File("/tmp/test.tiff"))
Changing to this corrects the error:
new GeoTiffWriter(Files.createTempFile("testTiff", "tiff").toFile())
The change has no side effects, as the test is just checking for instantiation, and does no processing / evaluation of the created GeoTiffWriter.
