### Apache Iceberg version 1.9.2 ### Query engine Spark ### Please describe the bug 🐞 I'm getting ConcurrentModificationExceptions [here](https://github.com/apache/iceberg/blob/05cd8b52e7d06d0d246475bd11f138d25947fd13/azure/src/main/java/org/apache/iceberg/azure/adlsv2/VendedAdlsCredentialProvider.java#L75) when this is called by Azure code by multiple threads as they close their `ADLSOutputStream`. When I made access to the map synchronized, the problem was solved. ### Willingness to contribute - [x] I can contribute a fix for this bug independently - [ ] I would be willing to contribute a fix for this bug with guidance from the Iceberg community - [ ] I cannot contribute a fix for this bug at this time -- This is an automated message from the Apache Git Service.
