LocalVariable object not able to return full signature that contains generics.

Example: I have crated Foo class with the following method:
public void test(){
   ArrayList<Integer> localVar = new ArrayList<Integer>();
}
After creating JavaClass from Foo and accessing test() method and its local 
variable, signature reported for localVar is "java.util.ArrayList", where 
Integer generic part is truncated. However, after inspecting the ConstantPool 
for the Foo class, it does contain CONSTANT_Utf8[1]
("Ljava/util/ArrayList<Ljava/lang/Integer;>;"). Why not simply set the 
SignatureIndex of the localVar to the correct index within the ConstantPool 
that also includes the Integer part, or allow LocalVariable to also 
getAttributes(), where the Signature attribute is properly set to the full 
signature that includes Integer, as for methods.
