imbajin opened a new pull request, #3341:
URL: https://github.com/apache/hugegraph/pull/3341

   Concurrent map growth could hash a key using one table generation and access 
another, losing entries. A competing chain update could also make removal 
report an existing key as absent.
   
   Hashing now uses the captured table's length, and removal retries a failed 
compare-and-set while the key is still present. Parallel regressions check 
reads, removals, retained values and final size while maps grow.
   
   Validation: the original implementation and the first partial fix fail the 
native regressions; the final candidate passes the IntMap suite, Java 17 clean 
compilation and EditorConfig formatting. Three independent reviews passed.
   
   Doc - No Need: this corrects internal collection behavior without changing 
configuration, APIs or persisted formats.
