any appreciated.

i resolved above error changing persistence unit name. possible use of multiple names. still when rid of exception new error has been occurred. following error :

root cause  java.lang.verifyerror: expecting stackmap frame @ branch target 18   in method org.beginningee6.book.item._persistence_isattributefetched(ljava/lang/string;)z @ offset 

i researched , found adding -xx:-usesplitverifier can solve problem. added variable still can not rid of error.
