I think this is not a bug if the code relies on the fact that an empty 
string is a singleton. This obviously is an immutable object and there 
is no public method to create different empty string. But a user can 
create different 1-character strings with same value (first create 
uninitialized a 1-character string and than fill a content). If some 
code fails when none of 1-character strings are interned, this obviously 
is a bug.
