10/17/2023, 4:31 PMHey! I just succeeded at running a test with TestContainer & Pulsar 3.1.0 on my MacBook M1 using the following versions:
• Pulsar 3.1.0 docker image
• Pulsar Client 3.0.0
• TestContainers 1.19.1
• OpenJDK 19
Could you please share more details? Versions used, some code...

10/17/2023, 5:13 PMIt’s a common issue, for other frameworks as well:

10/17/2023, 5:16 PMHere is how they solve it in Vert.x:
https://vertx.io/docs/4.1.8/vertx-core/java/#_macos_configuration
Unfortunately you need to add a native macos resolver at build time

10/17/2023, 5:20 PM@Christos this error is indeed common and should not make the test fail. Could you share your code so we can help you better?

10/17/2023, 5:23 PMIf workinig on localhost, it can be ignored (like in test containers), otherwise, the solution is described in the vertx.io documentation.

10/17/2023, 5:32 PMLooks like the custom resolvers are there:

10/17/2023, 5:34 PMBut maybe shading causes the problem:

10/17/2023, 5:36 PMSo in fact it looks like a bug @Christos probably the best way is to report it on GH
