On more question about "image/gif" format, as far as I understand this format
do not support the alpha as well, then why it works w/o exceptions?

>> Root cause: Support for alpha channel in JPEG is removed in JDK-8204187 <https://bugs.openjdk.java.net/browse/JDK-8204187> and this causes DataTransferer to throw exception saying unable to get Service provided for ARGB channel in for Jpeg.
>> Solution : Use RGB image without Alpha channel. This regression test was written to verify image data before and after DnD, so removing alpha channel will not affect its purpose.
