The icedtea packages are not reproducible. * The JDK provides jar files that did not undergo repacking (see ant-build-system), so they contain timestamps.
* The doc output contains files generated by javadoc, which contain more than one timestamp. Near the top is a comment: <!-- Generated by javadoc (version …) on Tue Mar 06 12:59:50 GMT 2018 --> A little further down (still in the head of the document): <meta name="date" content="2018-03-06"> * Some of the HTML files in the doc output (such as share/doc/icedtea/api/org/omg/PortableInterceptor/ORBInitInfoPackage/DuplicateNameHelper.html) also contain text like this: --8<---------------cut here---------------start------------->8--- <div class="block">org/omg/PortableInterceptor/ORBInitInfoPackage/DuplicateNameHelper.java . Generated by the IDL-to-Java compiler (portable), version "3.2" from ../../../../src/share/classes/org/omg/PortableInterceptor/Interceptors.idl Tuesday, March 6, 2018 1:41:31 PM GMT</div> --8<---------------cut here---------------end--------------->8--- * Some HTML files in the doc output have *lots* of differences. An example is share/doc/icedtea/api/javax/print/attribute/standard/PrinterMakeAndModel.html, which seems to be *empty* in the “-check” output. This is rather strange. -- Ricardo
