As you probably know, it is based on top of UDP. As you might know, NIO2, which Tomcat can optionally use, does not have support for UDP. UDP NIO2 support was apparently planned when it was originally introduced, but was removed due to schedule constraints. As a result, it is not possible to use NIO2 for HTTP/3 clients or servers. Is there going to be a plan to fix this ? It seems like a good JEP candidate, but there's no JEP in the index at the moment: https://openjdk.java.net/jeps/0 Rémy > > *2) JDK 13 EA build 12, under both the GPL and Oracle EA licenses, is > now available at **http://jdk.java.net/13**.* > > * Proposed - Schedule for JDK 13 [2] > o 2019/06/13 Rampdown Phase One > o 2019/07/18 Rampdown Phase Two > o 2019/08/08 Initial Release Candidate > o 2019/08/22 Final Release Candidate > o 2019/09/17 General Availability > * Recent Bug fixes of Interest > o Build 9: > + 8214719: Deprecate -Xverify:none option > + 8216360: Deprecate -XX:CompilationPolicyChoice > o Build 10: > + 8218995: Deprecate the -XX:FailOverToOldVerifier option > o Build 12 : 8160247: Mark deprecated javax.security.cert APIs > with forRemoval=true > + 8220050: Deprecate -XX:-ThreadLocalHandshakes > + Apache Lucene Reported - 8219448: split-if update_uses > accesses stale idom data > * Changes in this build [3] > > Rgds,Rory > > [1] https://mail.openjdk.java.net/pipermail/jdk-dev/2019-March/002718.html > [2] https://mail.openjdk.java.net/pipermail/jdk-dev/2019-March/002716.html > [3] Changes > < > http://hg.openjdk.java.net/jdk/jdk/log?rev=reverse%28%22jdk-13%2B11%22%3A%3A%22jdk-13%2B12%22-%22jdk-13%2B11%22%29&revcount=1000> > > in this build > > > -- > Rgds,Rory O'Donnell > Quality Engineering Manager > Oracle EMEA , Dublin, Ireland > >
