Follow up to "8313698: BaseMultiResolutionImage doesn't work as icon of java.awt.Window on Linux"

[Andrei Rybak]

Hello,

I've reported https://bugs.openjdk.org/browse/JDK-8313698 and, unfortunately,
there's some confusion in the ticket due to my poor choice of words for
describing the _default_ icon of the JFrame.  The default icon depends on the
vendor of the JDK, and it isn't the Duke icon for all of them.  As can be seen
from file "Capture_Windows.PNG" in the Jira issue, it can also be the coffee
cup Java logo.

Because the person who reproduced the bug (Praveen Narayanaswamy) used
two images of Duke for files icon32x32.png and icon64x64.png [1] as input for
the _custom_ icon with BaseMultiResolutionImage, it gets really confusing.
My reproducer, available on GitHub, just uses two images of the numbers "32"
and "64" [2] for clarity. I have updated the wording in the reproducer on GitHub
to stop mentioning the Duke icon.[3]

I hope this clarifies the ticket description.

[1] The images in the Jira issue right now are not of the resolution claimed
     in the filenames, but the resolution doesn't matter for the bug's
reproducibility.

     and
     https://github.com/rybak/foobar/blob/master/baz/src/main/resources/swing/icon64x64.png
     with honest resolutions, just to be as close as possible for the
actual use-case.
