It can be done that way and it will solve this specific problem but I did !Windows because even though linux/solaris GUI does not support spaces as of now, GUI is easy to change and can accomodate spaces in near future but CUPS library will not accomodate the spaces so it might fail in linux/solaris then.
Anyways, I am ok with making this mac specific

If we know that exceptional behavior (service name containing spaces) is only limited to Mac, then the check in test should be only Mac specific and not (!windows).

    This evaluation needs to go in the bug report, not (just) here.

    mac. shows spaces in the name in its GUI but "_" in the names
    reported by lpstat
    so it may be that the replacement is right but I'd still like to
    dig a bit here.
    Can you point to the code that does the " "->"_" replacement. I
    can't see it
    in CUPSPrinter.getAllPrinters().

As per http://hg.openjdk.java.net/jdk9/client/jdk/file/449518f6a468/src/java.desktop/unix/classes/sun/print/CUPSPrinter.java#l425 it gets the response from CUPS server and the printer names obtained from server is stored in jdk. In my case, even though I specified "Ricoh Aficio..." in GUI
the "nameStr" obtained from CUPS responseMap is "Ricoh_Aficio..."

    And you saying that

    PrintServiceLookup.lookupPrintServices(null, null)

    will return an array with a "null" element ?

No, sorry to "eat-up words". What I meant to say, lookupPrintServices(null, attributes) returns array with 0 elements as checkPrinterName() return false [as user is asking to find "Ricoh Aficio" and not "Ricoh_Aficio"]
resulting in getServiceByName() returning null
which in turn causes lookByName() in the testcase to return null

    That would be a bug.

        Hi All,

        Please review a small bugfix whereby it is seen that if we
        specify printer with space in its name, then
        javax/print/PrintServiceLookup/GetPrintServices.java fails
        citing NPE.

        Bug: https://bugs.openjdk.java.net/browse/JDK-8025439
        webrev:
        http://cr.openjdk.java.net/~psadhukhan/8025439/webrev.00/
        <http://cr.openjdk.java.net/%7Epsadhukhan/8025439/webrev.00/>

        The NPE happens because
        
http://hg.openjdk.java.net/jdk9/client/jdk/file/b1543c5eb8af/src/java.desktop/unix/classes/sun/print/PrintServiceLookupProvider.java#l460
        calls checkPrinterName() which checks it name contains letter
        or digit
        
http://hg.openjdk.java.net/jdk9/client/jdk/file/b1543c5eb8af/src/java.desktop/unix/classes/sun/print/PrintServiceLookupProvider.java#l433
        and returns null if has spaces
        so lookupPrintServices() gets null

        Now, if we remove this <space> check then also, it will not
        work as
        In system running with CUPS, refreshServices calls
        CUPSPrinter#getAllPrinters() which returns a set of printers.
        It seems it replaces " "  with "_" when populating the list
        for e.g Ricoh Aficio MP 5002 printer name is sent as
        Ricoh_Aficio_MP_5002 and stored in the list so we cannot have
        <space> in printer name.

        In Mac, it takes <sp> in printer name when we add printers but
        in linux, solaris it does not allow spaces in printer name
        during addition
        so in the proposed fix, a check for <sp> is added to make it
        automatic pass for non-windows (CUPS) system.

        Regards
        Prasanta
