dont be surprise with Javanese name ,
it may be same Batmen what you are thinking about
other common name are ,idra,vishnu,krishnu ,swatik,aditya,rama,devi sita,devi kushumawati,devi sri,sraswati ,visma ,ruchi,indrayu ,maheshvara,nakul,sahdeva
my subordinate having name Mohandas karam chand gandi ,we call him simply karam, because his father was highly influence by mahatma Gandhi
another one Sadam Hussain
because last name has no significance in Javanese society ,neither people give loud expression on name ,
so simply they chose name what they like ,
i have Hugh respect for Javanese philosophy ,culture and tradition ,they are very simple and deep rooted,
