Hi Joe, evenutally I have updated my webrev for this issue: http://cr.openjdk.java.net/~clanger/webrevs/8168664.1/
I've implemented your suggestion to add a property "jdk.xml.generatePrefix" which is true by default. I also added a testcase which tests the correct behavior with "-Djdk.xml.generatePrefix=false". Generally, I think namespace prefix generation at this place is not needed. Or would you know of or be able to construct a case where it is really required? If not, I rather think namespace generation at this place should be thrown out unconditionally. Maybe for JDK10? In case it is removed, it would render the test javax/xml/jaxp/unittest/transform/NamespacePrefixTest.java which was implemented recently by Alex for bug https://bugs.openjdk.java.net/browse/JDK-8167179 obsolete in its current form. However, the namespace generation function is still used some place for attribute namespaces. For JDK9 I can imagine the change of this webrev going in - however, as we already discussed, you would have to do a ccc for me. Thanks & Best regards Christoph From: Langer, Christoph Sent: Dienstag, 25.

Bug: https://bugs.openjdk.java.net/browse/JDK-8168664 Webrev: http://cr.openjdk.java.net/~clanger/webrevs/8168664.0/ I'm not 100% sure if this is the right way to go or if it would break some correct behavior elsewhere. But I think the current behavior is either not correct or at least it is not required to generate new xsl namespace prefixes if the namespace comes in as URI only to an xsl:element node. The interpretative transformer from the Apache Xalan project will also produce the expected output, different to the compiled XSLTC here. In the webrev, my changes to XslElement.java are only cosmetical/comments, the behavior does not change. In BasisLibrary.java I also took the opportunity to remove the $Id tag and the unused method "nodeList2IteratorUsingHandleFromNode". If you think my change is good, I'll also add a test that runs the transformation which can be found in the bug... Thanks & best regards Christoph
