Found suspicious code in the method sun.print.IPPPrintService#opGetAttributes which was introduced in JDK-8170578.
There is getAttMap field in IPPPrintService class.

    private HashMap<String, AttributeClass> getAttMap;

And it used like this in 'opGetAttributes' method:

   for (Map.Entry<String, AttributeClass> entry : responseMap[i].entrySet()) {
        if (!getAttMap.containsKey(entry.getValue())) {
            getAttMap.put(entry.getKey(), entry.getValue());
        }
    }

This call 'getAttMap.containsKey(entry.getValue())' will always result in false.
It seems it should be 'getAttMap.containsKey(entry.getKey())' instead.
