Generally speaking, because it's not possible to declare a local variable in
your Java program as a type that is the return address, as in:
int x;
String y;
ReturnAddress z; // not possible
As best I remember, ReturnAddressType can only be the type of a local
variable inside a JSR "subroutine". It is typically stored onto the stack
as the first instruction in the subroutine (invoked via JSR/JSR_W), so that
a RET instruction will know where to return.

Subject: [Q]: returnAddress and localVariable
Hi BCEL users
Here a simple question: Why the BCEL is rejecting the declaration of a local
variable of type Returnaddress ???
java.lang.IllegalArgumentException: Can not use <return address> as type for
local variable
at org.apache.bcel.generic.MethodGen.addLocalVariable(MethodGen.java:352)
