- Rebalance command when executed with 1.12.0+ locator and older servers, the command failed
- This was because the Rebalance function moved to a new package
- Similar problem with REST calls because of moving CacheRealizationFunction to a new package
- There was another problem where Serializable classes with UIDs were changed in couple of releases
- The variation of the UIDs caused deserialization issues when REST commands were executed from new locators and old servers.
