Unable to use Blackbird with Micronaut

[loicmathieu]

It's impossible to use the Blackbird module with Micronaut, it generates an exception.

The Micronaut team reports the issue may be inside Jackson itself, see micronaut-projects/micronaut-core#11253

Version?

[loicmathieu]

Micronaut 4.9 and Jackson 2.20.

[cowtowncoder]

Unfortunately we would really need a stand-alone reproduction here. Could be something simple, but can only investigate when problem occurs (regular test suite passes etc).

[loicmathieu]

Unfortunatly, it cannot seems to be reproduced easily at least with a simple Micronaut project using Jackson.
The only way I can reproduce it is buy adding this module to Kestra and start its webserver but I assume it's too complex.
I may have time later to give it another look.

[cowtowncoder]

Ok. Yes, sometimes that's how things are. There may be something with configuration that matters; perhaps a custom BeanSerializerModifier replaces initial List of BeanPropertyDefinitions with an immutable version, for example.

[yawkat]

feel free to ping me once you have a reproducer
