Examples of org.voltdb.exceptions.EEException

org.voltdb.exceptions.EEException
Exceptions thrown by native Execution Engine that should only be caught by Volt We don't throw exceptions directly from JNI for portability. Instead, this Exception has an error code which specifies the reason of the exception. Generally these should be errors that are not caused by the user and that are unexpected. They may be fatal and bring down the cluster, but they dont' have to if the code throwing the Exception knows that no data has been corrupted and that operation can continue.
