This PR is a follow-up to my previous attempt to resolve an IllegalArgumentException encountered when interning byte[] objects in Hollow which was subsequently reverted due to unforeseen issues. As suggested by @Sunjeet, proposed solution has now been implemented and tested.

Changes Made:

  • Applied the patch suggested by @Sunjeet, adding support for byte[] interning within ObjectInternPool.
  • Conducted thorough testing to confirm the fix addresses the issue without adverse effects on Hollow's functionality.

Acknowledgements:
Special thanks to @Sunjeet

Original description:
When loading states with byte[] as the primary key in Hollow, the ObjectInternPool throws an IllegalArgumentException. This issue occurs because the current implementation of ObjectInternPool does not support interning objects of type byte[], which is needed by HollowHistoryUI.

The proposed solution extends the ObjectInternPool functionality to handle byte[] effectively, allowing HollowHistoryUI to intern these objects without errors.

Current implementation throws exception:

Caused by: java.lang.IllegalArgumentException: Cannot intern object of type [B
