Hi Phil,
Please find the updated webrev:
http://cr.openjdk.java.net/~psadhukhan/8034239/webrev.01/
I checked JDK-8040139 also passed with this modification.

if the class is supposed to use the return value in this way what
about these lines :-
1209
1210 public boolean isIPPSupportedImages(String mimeType) {
1211 if (supportedDocFlavors == null) {
1212 getSupportedDocFlavors();
1213 }
It looks to me as if what you should really be doing is modifying
the last few lines of getSupportedDocFlavors() as you are using
the return value to update the variable which it should have
assigned itself.

Hi Phil,
Please review a print service fix for jdk9
Bug: https://bugs.openjdk.java.net/browse/JDK-8034239
webrev: http://cr.openjdk.java.net/~psadhukhan/8034239/webrev.00/
The issue was lpstat -v was reporting 2 printer service but
PrintServiceLookup.lookupPrintServices() list only 1.
#lpstat -v
device for tta_printer:
ipp://<internal-printer-ip>/printers/tta_printer
<ipp://st-tta-adc-02.us.oracle.com/printers/tta_printer>
device for Xerox-WorkCentre-4250: socket://spb04p12.ru.oracle.com:9100
but lookupPrintServices() listed only "Xerox" printer and not
"tta_printer".
It seems "tta_printer" was added using
*lpadmin -p printer-name -E -v device -m ppd *
so it becomes a "Remote Printer" and even though Java sees that
printer, it calls getUnsupportedAttributes() on that printer service
to see if that printer matches the DocFlavor.
In this case, this remote printer does not have any supported doc
flavor listed so when getSupportedDocFlavors() is called, it does not
see any "document-format-supported" attribute.
Although JDK-8040139 fixed this problem by adding
DocFlavor.SERVICE_FORMATTED.PAGEABLE and
DocFlavor.SERVICE_FORMATTED.PRINTABLE
to the supported DocFlavors since as per spec,
as per spec
/https://docs.oracle.com/javase/8/docs/api/index.html?javax/print/PrintService.html//
//it clearly says, /
getSupportedDocFlavors()
/Returns:/
/Array of supported doc flavors, should have at least one element./
the returned flavours are not populated to supported DocFlavors
called by IPPPrintService.java#getUnsupportedAttributes() ->
isDocFlavorSupported() so "supportedDocFlavors" was still false for
this case.
I added a fix to populate the PAGEABLE & PRINTABLE docflavor to
"supportedDocFlavors" and tested in sqe machine and found it working.
I could not add a regression testcase as it involves adding a "remote
printer" using lpadmin command. I would add "noreg-sqe" to the bug.
