large amount of com.microsoft.kiota.store.InMemoryBackingStore$Pair objects are allocated, memory leak?

Describe the bug

trying to use the delta api and observed 10s of gigabytes of ram usage from this sdk.

Expected behavior

memory consumption should not be this large for a library doing http requests.

How to reproduce

just periodically call the users/groups delta api and try to persist the user/group models somewhere, you will see the ram usage steadily rising.

SDK Version

6.20.0

Latest version known to work for scenario above?

No response

Known Workarounds

none found atm.

Comienza reproduciendo el problema con la users/groups delta API en Java SDK 6.20.0 mientras se persisten los modelos; después, inspecciona las asignaciones de com.microsoft.kiota.store.InMemoryBackingStore$Pair notificadas. Compara el uso de memoria entre llamadas repetidas en las configuraciones de Java y OS indicadas; se considera terminado cuando el crecimiento constante y la retención excesiva de Pair estén explicados y resueltos, con una comprobación de regresión para el escenario.
