hi, I created an issue at kryo with a simple project that reproduces the problem, but still asking here in case anyone knows a solution:
https://github.com/EsotericSoftware/kryo/issues/462 basically, I get an error trying to serialize a simple tree like structure, the error happens with a 2 node, 1 leaf tree so it's not a recursion problem caused by the size of the data. anyone knows a way to avoid this error? also, in the repo I tried with the 3 latest stable versions of kryo (2.24.0, 3.0.3 an 4.0.0) and 4.0.0 seems to fix it, I tried building flink and testing the update and with 3.0.3 it seems to work, but the build fails for 4.0.0, didn't looked much into details since I hadn't much time. I think at least moving to 3.0.3 would be a good thing in case this is true: https://twitter.com/novoj/status/780693354610880514
