<AWT Dev> Bug Report (Review ID: JI-9024378) - cannot copy to the system clipboard using the mimetype = 'image/svg+xml'

This is a duplicate of a bug report originally issued to openjdk as 
JI-9024378, see message below. However, that report appears to have 
gottern lost, so I am re-submitting it here. If I try to create the 
mimetype 'image/svg+xml' on the clipboard, I will instead get the 
mangled mimetype = 'JAVA_DATAFLAVOR:image/svg+xml; class=java.io.InputStream'.
The code for generating the mimetype is SVGCopy.java, attached here.
The code for verifying the mimetype is the Windows program 
Clipview.exe, available at: 
Due to the fact that the mimetype has been mangled, it is not 
possible to paste data of this type into Inkscape : https://inkscape.org/

My java jdk is: java version "1.6.0_16"
My system is : Microsoft Windows [Version 6.1.7601]

Thank you for your consideration
