mibo updated OLINGO-1586:
-------------------------
Fix Version/s: (was: (Java) V4 4.8.0)
> ConcurrentModificationException while accessing EDM object
> ----------------------------------------------------------
>
> Key: OLINGO-1586
> URL: https://issues.apache.org/jira/browse/OLINGO-1586
> Project: Olingo
> Issue Type: Bug
> Components: odata4-client
> Reporter: Prasanth Ganesh Rao
> Priority: Critical
>
> We have implement a cache that keeps the EDM object and then reuses the same
> in subsequent calls. What we are observing is when we try to access the EDM
> object via multiple threads concurrently, at times we get
> ConcurrentModificationException exception. The issue is typically observed
> right after updating the cache with new EDM object.
> Stacktrace:
> java.util.ConcurrentModificationException
