[jetty-dev] JDK 11 support on 9.4.12

[Michele Rossi]

hi all,

I have just tried to run my web app on Jetty 9.4.12 and I couldn't get it
work when compiling it with target = java 11.

This is the type of stuff that I was getting:

Looking into it a bit I noticed that only ASM 7.0 which is still in beta
supports JDK 11 classes and that Jetty 9.4.12 links ASM 6.2
(jetty-annotations module).

Does the above make sense or am I making some other type of mistake?

If indeed Jetty 9.4.12 can not run webapps compiled with Java 11 as target,
when do you guys think you will issue a version that fully supports it?

I am asking just out of curiosity, happy to stay with Java 10, I am very
well aware that I am not paying for your time :)

thanks for your help.

It's correct.

9.4.13.
We are waiting for ASM 7.0 and we'll link against that.

Would be great if you can try branch jetty-9.4.x-2941-asm_jdk11 and
report back if it works for you.

Thanks!
