Subject: [PATCH] Replace HashSet with fastutil's ObjectOpenHashSet in
|
|
HashTreeSet
|
|
|
|
HashSet sometimes uses compareTo() instead of equals() and this breaks the comparison of net.minecraft.server.NextTickListEntry (the only place where HashTreeSet is used).
|
|
|
|
In this cases duplicate entries could be added to the HashSet of HashTreeSet, because NextTickListEntry.compareTo() does not return 0, even if NextTickListEntry.equals() returns true.
|
|
|
|
ObjectOpenHashSet never uses compareTo(), so the inconsistencies of NextTickListEntry cause no problems.
|
|
|
|
Fixes https://github.com/PaperMC/Paper/issues/588
