For using a sequence generator, we need to follow the following steps :
a) CREATE SEQUENCE USER_SEQUENCE START WITH 1 INCREMENT BY 10;
b) @SequenceGenerator(name="USER_SEQUENCE_GENERATOR", sequenceName="USER_SEQUENCE",initialValue=3, allocationSize=4)

NOTE: The initialValue and allocationSize values are different in databaseSequence and SequenceGenerator.

What will happen in this case? Will it throw some error or Which initialValue & allocationSize value will be used ?
 
It is sorta covered in the JavaRanch Style Guide.
