This version looks fine to me.

Yes, those constructors should be type-safe.  Perhaps that was done to save 
code in the caller, but that is a small price to pay to avoid errors in the 
future, and it makes sure there is a backup plan for different kinds of 
buffers...

Hi, Ajit.
What about other cases in Raster.java, where the DataBuffer is passed
as a parameter? Probably we can simplify the code and find all such
issues if we changes the ByteInterleavedRaster/etc. For example:

ByteInterleavedRaster(SampleModel sampleModel,DataBuffer
dataBuffer,...) to

ByteInterleavedRaster(SampleModel sampleModel,DataBufferByte
dataBuffer,...)

Because we throw an exception in such cases anyway:

if (!(dataBuffer instanceof DataBufferByte)) {
      throw new RasterFormatException("ByteInterleavedRasters must have "
+ "byte DataBuffers");
}

And the compiler will help us, what everybody think about it?

Hi,

Bug : https://bugs.openjdk.java.net/browse/JDK-6353518

Issue : (Text from bug description)

An attempt to create a WritableRaster via
Raster.createWritableRaster(SampleModel sm, DataBuffer db, Point
location) using a custom DataBuffer causes an erroneous
RasterFormatException.
Apparently the reason for this bug is that IntegerComponentRaster
insists on being passed an instance of DataBufferInt rather than
just a DataBuffer with a DataType of TYPE_INT.
This is quite annoying since DataBufferInt is declared final and
thus cannot be extended.

Fix :

The last line of Raster.createWritableRaster() method already has a
way to handle generic case if the input does not match any of the
cases in switch statements in that method.

The fact that  " *InterleavedRaster() constructors throw exception
if DataBuffer passed to them does not match the expected type" was
ignored earlier.

This fix adds a check of "DataBuffer type" before creating
respective
*InterleavedRaster() objects.

It constructs the SunWritableRaster in case DataBuffer type does not
match any data specific DataBuffer classes (DataBufferByte,
DataBufferUShort, DataBufferInt)

Request to review webrev containing this fix :
