Stop explicitly blocking Vanilla Method Profiler At the time this was re-added, there was concern around how the JIT would handle the system property that enabled it. This shouldn't be a problem, and as such we no longer need to block access to it. The Vanilla Method Profiler will not provide much to most users however there is no harm in providing it as an option. For most users, the recommended and supported method for determining performance issues with Paper will continue to be Timings.

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

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.
