public class ValidationException
extends java.lang.Exception

This exception is thrown to indicate that a data object has invalid or corrupt data. It is generally thrown by persisters or loaders. UI validation should prevent this exception from appearing in application code, but in many cases, validation is not guaranteed to occur on inbound data (such as an import feed).
