Null Attribute Remover

Version 1.5 – UUID Validation Fixes & Smarter Filtering

Highlights:

• Improved detection logic for attribute modifier UUIDs

• Prevents false positives from vanilla attribute names

• Adds new configuration option to control global UUID deduplication

Fixes & Improvements:

• Fixed: Vanilla attribute names like minecraft:armor.boots or base_attack_damage were incorrectly flagged as invalid UUIDs.

• The plugin now skips UUID parsing unless the modifier name looks like a real UUID (36 characters, 4 dashes).

• Improved: Safer handling of non-UUID-like names. These are no longer treated as errors and won’t be removed unless truly broken.

• Cleaned up logging for skipped UUID parsing — now clearly says when something was intentionally ignored due to being a vanilla name.

New Config Option:

ignoreDuplicateUUIDsAcrossAttributes:Allows modifiers to share UUIDs across different attributes, preventing false-positive removal of legit modifiers (e.g., damage and toughness sharing a UUID).

ignoreDuplicateUUIDsAcrossAttributes: true

v1.4.1 - Logging Tweaks & Sanity Preservation

• Added log-invalid-uuid-names config optionYou can now suppress log spam from UUID-like modifier names (e.g. "armor.boots") that previously cluttered the console with lines like:Skipped bad UUID: armor.helmet.

• These logs are still detected and cleaned — they just no longer scream about it unless you want them to.

• Minor config cleanup and prep for quieter deployment environments.

NullAttributeRemover v1.4

Removed

• Entire UUID-fixing mechanism — no more attemptFixInvalidUUIDs setting or code paths.
• Config option: attemptFixInvalidUUIDs
• Any logic invoking UUID.nameUUIDFromBytes(...) or generating replacement modifiers.
• Deferred fix queues, replacement-runner code blocks.
• All references to replacing invalid UUID entries with newly generated ones.

Changed

• Simplified cleanAttributes() method:

  • Now strictly removes invalid modifiers (blank name, null UUID, invalid amounts, duplicate UUIDs).
  • Removed attempts to patch or "fix" invalid UUID values.

• Validation logic now:

  • Issues warnings for UUID-like names when logUUIDLikeNames is enabled, but does not treat them as removal criteria.
  • Removes modifiers whose name equals their UUID (likely injected debug values).

• Removed all code paths using deferredFixes, fixQueue, or replacement fallback logic.

Log Behavior Updates

• Core clean-up logs:

  • Only logs removal events (e.g. “Removed X invalid modifiers”).

• Warnings for invalid UUID strings are still configurable via debugLogs.

• No more log entries indicating “Fixed X modifiers” — only removal summaries.
