Java 10 FYI

[javadevmtl]

Tested some of our vertx apps with Java seem to run fine so far. Only some Netty warnings which I assume will eventually get fixed...

WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by io.netty.util.internal.ReflectionUtil (file:/opt/merchant-api/lib/merchant-api-java10-fat.jar) to constructor java.nio.DirectByteBuffer(long,int) WARNING: Please consider reporting this to the maintainers of io.netty.util.internal.ReflectionUtil WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release

This should be fixed on Netty 4.1.21.

So far, Vert.x is using Netty 4.1.19: https://github.com/vert-x3/vertx-dependencies/blob/master/pom.xml

Not sure what's in between those versions, but indeed it would be nice to have these warnings fixed :)

we're planning to upgrade to 4.1.21.Final, there is an open issue for it.

Hi Julien,

I assume that the issue you referred to is this (#2390), although not specifically related to a release.

Besides this, is there any mention about Vert.x support of newer Java versions (currently 10)?

Still continuing the drifting from the main topic of this thread :-), I noticed that Starter did not include version 3.5.1.

Thanks!

Currently we only test with Java 9 because we have a blocker with Java 10 (MVEL templates).

We plan actually to get rid of MVEL and replace with pure Java code in 3.6.0 (contributions welcome :-) ) so we can test with Java 10 and beyond, this is high priority.

3.5.2 will continue with Netty 4.1.19.Final because there is no corresponding grpc version that ships with more recent Netty

3.6.0 will likely have its Netty version upgraded as soon as grpc releases it.

I would like to have  the grpc transport reimplemented with Vert.x HTTP/2 support to get rid of this Netty coupling (contributions welcome again) which is ok-ish (as they release often) but it would be better without.

Still continuing the drifting from the main topic of this thread :-), I noticed that Starter did not include version 3.5.1.

Daniel is supposed to contribute to the starter changes that will include support for 3.5.1
