stack commented on HBASE-20894:
-------------------------------
bq. So the old code works because there's only one id ever registered?
This code has been in there since the original commit. Probably. When I look at
it, its like something that had a purpose once but the context was undone.
bq. Serializing class name isn't going to help us because it will be some
garbage anonymous name...
You are right. Class would have to be named for my nonsense to work.
> Move BucketCache from java serialization to protobuf
