The regression test test/sun/awt/image/RasterTester/BytePackedRasterTest
attempts to create 1, 2, 4, and 8-bit BytePackedRasters. This raster type
was restricted to 1, 2, and 4-bit rasters only in Merlin (RFE 4425264).
Therefore, the following exception is produced when trying to construct an
8-bit raster:

Exception in thread "main" java.awt.image.RasterFormatException: BytePackedRasters must have a bit depth of 1, 2, or 4
        at sun.awt.image.BytePackedRaster.<init>(BytePackedRaster.java:164)
        at sun.awt.image.BytePackedRaster.<init>(BytePackedRaster.java:80)
        at BytePackedRasterUnitTest.<init>(BytePackedRasterTest.java:23)
        at BytePackedRasterTest.<init>(BytePackedRasterTest.java:93)
        at BytePackedRasterTest.main(BytePackedRasterTest.java:114)

BytePackedRasterTest should be updated appropriately.
