One *potential* issue with this approach is that LTS is not defined in OpenJDK as far as I know. The LTS versions are a business decision of each distributor. For now, they have all aligned on 8, 11, 17, but nothing guarantees that this will stay so. What if different vendors LTS different versions? Suppose that Valhalla and Loom add very attractive features in JDK 19 (big performance enhancements, leads to big money savings on hardware, leads to economic incentives to use these, leads to requests to support these), now vendors can declare JDK 19 as LTS, and what will JavaFX do? In OpenJDK all versions are treated equally as it is a spec and not a business model. Should JavaFX be coupled to business models? Maybe Gluon has some insights since they give JavaFX LTS support. A second point, as Michael Strauß mentioned, is that maybe we should see what features are going to be delivered in the next versions and judge if there's something attractive enough for library developers to base our decision on. Sealed classes from Amber are certainly one of them. Panama might provide handy features for JavaFX's interfacing with native code, like Foreign Memory Access, though I didn't look into it in detail. Valhalla is certainly too far away to consider, and Loom is rather irrelevant for JavaFX and GUIs in general. If anyone has insights into relevant upcoming features I'll be happy to learn. - Nir On Tue, May 18, 2021 at 6:17 PM Kevin Rushforth <kevin.rushfo...@oracle.com> wrote: > A very timely question.
