Contributions summary:Petr's commits focus on enhancing the Hazelcast data platform, particularly improving the IMap interface. They modified the IMap interface to make collection clones immutable, throwing exceptions on modification attempts, and moved internal implementations to internal packages. These changes, which included code modifications in the IMap.java and BasicMapTest.java files, directly addressed issues related to data consistency and immutability, reflecting a focus on backend logic and data structures within the Hazelcast environment. They have also worked on implementing improvements to support the native memory framework integration for Hazelcast.
