commit aa7983e028caffedc37fedc07276de193ff5f5ca Author: orisgarno <[email protected]> AuthorDate: Tue Jan 7 20:36:30 2025 +0700 fix(java): Compatible mode on de/serialize api failed to deserialize (#1996) ## What does this PR do? Read and write class data on COMPATIBLE mode for de/serializeJavaObject api. When COMPATIBLE mode is on and need to serialize and deserialize different POJO, users are required to register classes those are going to be serialized or deserialized. ## Related issues <!-- Is there any related issue?
