INFO | jvm 1 | 2011/09/01 10:43:07 | 2011-09-01 10:43:07.583 Oracle Coherence SE 3.5.3/465p3 <Info> (thread=EventPersistenceBufferTransformer-Thread-10, member=3): Overflow Map has received an inexplicable event from the front map; such an event should not have been possible to occur. The Overflow Map will arbitrarily interpret the event in order to maintain its own internal consistency. The likely origin of the event is direct modification of the front and/or back maps managed by the Overflow Map, a MapListener making re-entrant modifications to its source map, or an ObservableMap implementation that reacts to the Map API in a manner inconsistent with the specification (e.g. actively modifying its contents in a manner that differs from the sequence of API calls made against it). This Overflow Map instance will not repeat this warning, and will attempt to silently compensate for subsequent similar event irregularities.
