Hi Martjin, could you add the output of mvn --version? Thanks! 😄

[aalmiray]

It may be related to #77

I've got the same compilation error when running a full build with JDK 11, however the build succeeds (locally) if JDK 15 is used. The build is currently broken on GitHub actions even if JDK 15 is used (due to a timing issue when running the vert.x test).

Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)

[aalmiray]

Thanks @karianna. May I suggest you to try out the build with JDK 15+?

[karianna]

15 works :-)

[gunnarmorling]

Thanks for reporting back. So we should get to the grounds of this, I don't see any fundamental reason why 11 shouldn't work.

[aalmiray]

Indeed. Tests were working fine with Vert.x 3.x. Upgraded to Vert.x 4.x as soon as it was released. Have to check if there's a difference in behavior between the two versions. Also, Awaitility might need to be reviewed.

[gunnarmorling]

Oh, that's interesting. Classloading structure changed a fair bit between Vert.x 3 and 4, AFAIK.

…

[aalmiray]

I suppose we could switch back to 3.x for the sake of automated tests. Yet the cause of the breakage with 4.x would still have to be found.

[aalmiray]

Alright. Moved Vert.x back to 3.9.5 and gave a twirl. Test breaks with JDK11 (with the same reported exception) but succeeds with JDK15. This might not be related to the Vert.x version. Stumped.

[aalmiray]

Tried different distros of 11.0.10. All of them break with the same error

Java version: 11.0.10, vendor: Azul Systems, Inc., runtime: /Users/aalmiray/.sdkman/candidates/java/11.0.10-zulu/zulu-11.jdk/Contents/Home
Java version: 11.0.10, vendor: Amazon.com Inc., runtime: /Users/aalmiray/.sdkman/candidates/java/11.0.10.9.1-amzn
Java version: 11.0.10, vendor: BellSoft, runtime: /Users/aalmiray/.sdkman/candidates/java/11.0.10-librca
Java version: 11.0.10, vendor: AdoptOpenJDK, runtime: /Users/aalmiray/.sdkman/candidates/java/11.0.10.hs-adpt
Java version: 11.0.10, vendor: GraalVM Community, runtime: /Users/aalmiray/.sdkman/candidates/java/21.0.0.r11-grl

However JDK 12 (had to use SapMachine as that's the only version of 12 provided by SDKMAN!) works. Azul's 13 works as well.

Is there something weird going on with JDK 11?
