Hi All,
Please review a testbug fix for jdk9 for an issue where it it seen
that PageRanges option is disabled in printer dialog in ubuntu16.10.
Bug: https://bugs.openjdk.java.net/browse/JDK-8170578
webrev: http://cr.openjdk.java.net/~psadhukhan/8170578/webrev.00/
Issue was, in ubuntu16.10 the attribute map [obtained here
http://hg.openjdk.java.net/jdk9/client/jdk/file/dc658d7dde90/src/java.desktop/unix/classes/sun/print/IPPPrintService.java#l1767]
does not have
"pageranges-supported" attribute returned by CUPS
so this category is not added to supported categories
[http://hg.openjdk.java.net/jdk9/client/jdk/file/7f09d558b044/src/java.desktop/unix/classes/sun/print/IPPPrintService.java#l1030]
so isAttributeCategorySupported() called by ServiceDialog returns false
[http://hg.openjdk.java.net/jdk9/client/jdk/file/7f09d558b044/src/java.desktop/share/classes/sun/print/ServiceDialog.java#l1141]
resulting in PageRanges option getting disabled.
Fix is to check if PageRanges category is supported in underlying
platform, only then proceed with the test.
