EntityDamageByEntityEvent called more than should.

[cb31455]

Expected behavior

EntityDamageByEntityEvent should be called 1x per dmg received on player. if i know well (as experienced) maximum 1 instance of damage should taken by player per every half second no matter how many enemy attacks at the same time (at least this was till 1.21 / 8d91b85Prioritize vanilla commands in function parsing (#11011)).

Observed/Actual behavior

EntityDamageByEntityEvent called multiple times if more enemy attack even this happens when 1 attack does dmg only.

Steps/models to reproduce

Let multiple enemies attack at the same time. 2 attacks registered / sec as received dmg, but EntityDamageByEntityEvent called way more times. This happens since 1.21 4d20922Updated Upstream (Bukkit/CraftBukkit/Spigot) (#11024) update.
I made a picture, where red numbers "dmg taken" calculated by EntityDamageByEntityEvent in my plugin. that 4 red number happened under 0.5 sec.

Plugin and Datapack List

Own plugin (ChipsTm), which worked nicely till patch 1.21 8d91b85Prioritize vanilla commands in function parsing (#11011)
Chunky. works fine.
Datapacks: vanilla, file/bukkit, paper

Okay found the issue 👍 Upstream issue, will look into a fix.

#11045 should fix this, until merged there is a server jar to test with on the PR.

that test server jar working fine in this case (minimal testing)

edit: have lagg issue on that version.
edit2. there was a lagg issue since first 1.21 when too much enemy mob handled by my plugin. it looks like this dissapeared in 45+ versions, but just came back in this test file.
