Hi,

the Goals section of the "Incubator Modules" JEP [1,2] reads as follows: "The incubation lifetime of an API is limited: It is expected that the API will either be standardized or otherwise made final in the next release, or else removed."

JEP 11 predates the shorter release cadence, hence the current wording. While not strictly incorrect, and in light of the shorter cadence, this wording could be better.

OpenJDK 9 was shipped with the httpclient incubator module and I havn't seen any effort to standardize this API in Java 10/18.3.

While there are no plans to standardize this particular API in Java 10, there is ongoing work to move it towards standardization. This work has been happening in the JDK 10 sandbox, and recently moved over to the new JDK sandbox ( on the http-client-branch [1] ).

Does this mean that the new httpclient library will be removed from OpenJDK 10/18.3?

It is my understanding that the folk working on this API are planning to "refresh" the current incubator code in 10, based on the work in the sandbox. Expect to see announcement to this effect on net-dev shortly.

Or should we better revise JEP 11 and rephrase the Goals section to something like:

"The incubation lifetime of an API is limited: It is expected that the API will either be standardized or otherwise made final in the next LTS release, or else removed."

I don't think that it is appropriate, or even necessary, to tie incubating features to LTS releases. I will do a full review of JEP 11 and reply shortly.
