Subject: [PATCH] Fix concurrenct access to lookups field in RegistryOps
|
|
|
|
The concurrent access occurs on the Netty IO threads when
|
|
serializing packets. Thus, it seems it was an oversight of
|
|
the implementator of this function as there are typically
|
|
more than one Netty IO thread.
|
|
|
|
Fixes https://github.com/PaperMC/Folia/issues/11
