Some of my colleagues at Entrust noted that <a href="https://bugs.openjdk.java.net/browse/JDK-8180834">JDK-8180834</a> was backported to the Oracle 7u191 b31 release (<a href="https://www.oracle.com/java/technologies/javase/7-support-relnotes.html#7u191-b31">https://www.oracle.com/java/technologies/javase/7-support-relnotes.html#7u191-b31</a>). Essentially it adds GCM Ciphersuite support into JDK 7. I was able to download 7u191 from Oracle’s support site and verified GCM cipher suites are working.<o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText>However, they want to make use of OpenJDK 7, but it appears OpenJDK 7u191 (and later versions) do not contain the backport. <o:p></o:p></p><p class=MsoPlainText><o:p> </o:p></p><p class=MsoPlainText><span style='color:black'>We noticed a couple of things. The fix for </span><a href="https://bugs.openjdk.java.net/browse/JDK-8180834">JDK-8180834</a> says it <span style='color:black'>is in “branch master” </span>of openjdk 7 (<a href="https://hg.openjdk.java.net/jdk7u/jdk7u/jdk/file/tip/src/share/classes/sun/security/ssl/CipherSuite.java#l1316">CipherSuite.java</a>). If you check the line referenced in this link it says (<span style='font-size:9.0pt;color:black;background:#BFDFFF'>Unsupported cipher suites from RFC 5289</span>) [<a href="https://tools.ietf.org/html/rfc5289">RFC5289</a>]. This is the <a href="http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/rev/def2e05299b7">changeset</a> that openjdk made to support GCM in JDK8, If you look at the changes in <a href="http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/diff/def2e05299b7/src/share/classes/sun/security/ssl/CipherSuite.java">CipherSuite.java</a> the unsupported GCM cipher suites are now implemented. In the comments of issue <a href="https://bugs.openjdk.java.net/browse/JDK-8180834">JDK-8180834</a> it says “Pushed changes to Master”, but what master? Is it a private master? The issue says it is resolved, but it is not closed. These things make us suspect that the changes are not in OpenJDK. <span style='color:black'><o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoPlainText>Do changes made in master not get automatically picked up by OpenJDK?
