Tests of examples/http-server failing

[redkhalil]

I have encountered this issue while following the example code and was able to reproduce it on the example code itself.

Testing started at 7:22 AM ...
SLF4J: Class path contains multiple SLF4J bindings.

Hmm, strangely, I've switched from OpenJDK 1.8.0_312 to Oracle JDK 1.8.0_311 and the tests are passing (both the finatra test - above - and the tests for my service). Can you advise if there is any dependency on a specific version of JDK. What are you guys using for development and production?

That's odd. From looking at the stacktrace in your file, it looks like this might be a way that netty is incompatible with JDK 1.8.0_312? We use an older version of the JDK internally. I'm not sure what the github workflow for jdk8 uses. Would you mind filing a ticket with their project?

@mosesn the CI action uses OpenJDK 1.8.0_332:

Run java -Xmx32m -version
openjdk version "1.8.0_332"
OpenJDK Runtime Environment (Zulu 8.62.0.19-CA-linux64) (build 1.8.0_332-b09)
OpenJDK 64-Bit Server VM (Zulu 8.62.0.19-CA-linux64) (build 25.332-b09, mixed mode)

The recommendation would be that users be at least on that version.

FWIW, this looks like a reported issue with Netty: https://github.com/netty/netty/issues/12119 and potentially specific to the Homebrew version of JDK8 being installed.
