create em1
//em1 start transcation tx1
tx1.start
Object r = getData();
em1 tried to delete r //code hangs here
tx1.commit


Object getData(){
create em2
return data found using em2
}

Answer 1

Don’t create an em2. Pass the em1 as a parameter to getData() method. Doing so, you’re operating only one em1.

I don’t know exactly, but it seems that em1 is putting lock on the related table, so you can’t do anything outside.
