When there is an error in the MDB,is the same instance of the MDB used for the retry? How can I check it? Is there any API in JAVA that tells me the unique attribute of an object?

When a message is re-tried, same instance of MDB may not be used.
You can find the uniqueness of an object by using identityhashcode.
