In previous releases, entries in the .odt part of the database did not get garbage collected. Consequently, if objects were deleted, you might have noticed the size of the .odt file growing. Release 1.0 Beta 4 adds an incremental Object Table Garbage Collector to collect these entries. Note that this is not a persistent object garbage collector. OSHashtable class has a new method.
OSDictionary class has a similar new method.
4 Three methods were moved from the COM.odi. Persistent class to the COM.odi. This is a compatible change that does not invalidate any code. With this beta release, the Class File Postprocessor automatically takes care of this issue in most cases. On the rare occasion that you manually annotate a class, you need to carefully choose the definition of the hashCode method .
