I am running res client (Redisson) on wildfly server and for few cache key. I am getting below exception.
Same code works on SpringBoot and standalone Java program. But fails on Wildfly.
Any help/suggestion is appreciated.
Caused by: java.io.IOException: java.io.IOException: :Failed to instantiate ‘com.xxxx.columnInfo.StandardColumnInfo’. Register a custom serializer implementing instantiate or define empty constructor.

For now I overridden BasicCodec and wrote my own codec class. Which works fine as SerializationCode.
I would suggest you to use MarshallingCodec as FSTCodec has a stability issues. Even Redisson has made Marshalling Codec as its default codec. The best part is that it can serialize almost all objects.
