Allon Mureinik has submitted this change and it was merged. Change subject: engine: Deprecate new Guid() ...................................................................... engine: Deprecate new Guid() Guid's default constructor created a new Guid object equal to Guid.Empty, which is quite redundant since Guids are immutable. Moreover, the default constructor just delegated to the String constructor, forcing an expensive UUID.fromString(EMPTY_GUID_VALUE) to be called on each invocation of new Guid(). In order to solve the performance issues here, the following was done: 1. The default constructor was changed to call the cheap UUID constructor instead of the expensive String constructor. 2. The default constructor was changed to private and marked as @Deprecated so it won't be called externally. Unfortunately, it could not be removed completely due to GWT limitations. 3. All the usages of new Guid() we removed and replaced by Guid.Empty for production code or by Guid.newGuid() for testing code (in order to provide some randomness, and hence, better robustness for the test).
