Do you know whether Flight Recorder will be a non-commercial feature in Oracle JDK 11 and later? The reason I'm asking is because AppCDS which was a commercial feature in Oracle JDK 8 and is a non-commercial feature in OpenJDK 10 will

I am not aware of any such plans. There is a supported API starting with Java 9 http://hirt.se/blog/?p=870 but it is "JDK" (Open/Oracle JDK and derivates) specific and lives in the jdk.jfr module and pac

I don't think there is a plan to standardize it. They "just" move the code from the Oracle repo to the OpenJDK repo. I wouldn't assume J9 or Zing will adopt this.

From what I understand the goals are similar but the approaches are different. - Shenandoah uses Brooks-style forward pointers whereas ZGC uses colored pointers and off-heap forwarding tables. - Shenandoah could in theory run on Windows, AF

Eve at 6k+ simultaneous players has a 10s tick rate due to TiDi. At 6k+ simultaneous players Eve isn't actually playable. I don't think there's an other game with a 1s tick rate, AFAIK Eve has the worst tick rate in the busin

I would say it depends, its quite easy to unknowingly depend on non-standard behavior that can break like HashMap iteration order. What often causes issues is that every release has a new byte code version and the ecosystem relies heavily o

Also old APIs can be removed part of the every 6 months feature releases. In theory an API can be deprecated in Java 10 and removed in Java 11.

Oracle offers support only for LTS releases. Oracle does not offer support for Java 9 and will not offer support for Java 10.

In Java land the JDBC driver is supposed to do that. If it doesn't then that's a bug in the driver. If it's a bug in the JDBC driver then the fix needs to go into the JDBC driver, especially if the driver is on GitHub. The pr

Nope, it makes things (a little bit) worse because now you also have to start up a module system.

It sounds interesting until you remember what a hassle native compilation is: 1. you need to compile on the exact same CPU make on model that you will run on (for now there's not cross compilation) 2. you need to compile with the exact

I'm really not a fan of these "clever" hacks that rely on compiler internals. That doesn't even work on ecj.

An annotation processor does not seem to be a good fit here. Annotation processors can only generate new classes, not modify existing ones. So you would have to make all classes abstract and then generate non-abstract ones that have a #chil

You're correct. In the old days that was the case. They were shared but only for money. These days Tomcat, TomEE and Payara can't claim Java EE compliance because they don't have a TCK. It is not clear to me wether this would

Nope, this is Oracle stop caring about Java EE. They are not doing this for Java SE as long as they are caring about Java SE. I also doubt IBM still cares about Java EE. Their last JSR (Batch/JSR-352) was particularly disgusting and se

Yes, if the Payara guys manage to take over the project, do more frequent releases and pull off some major refactorings. I am not sure they have the resources.
