[Cs5500] Strange behavior of FullyQualifiedClassName.print

[Ahmed Abdelmeged]

Hi Rashmi,
  Thanks for pointing this out.

The extra space is inserted by the "*s" below. This code is taken from
java.lib.cd

nogen List(X) = Cons(X) | Empty(X).
nogen Cons(X) = <first> X *s <rest> List(X).
nogen Empty(X)= .

Unfortunately, we cannot change *s to "." in this definition because this
will change the way Lists are written throughout the whole application. List
is also used for Requests, Responses, and ProtocolSpecs.

DotSeparatedList(X) = DotSeparatedCons(X) | DotSeparatedEmpty(X).
DotSeparatedCons(X) = <first> X "." <rest> DotSeparatedList(X).
DotSeparatedEmpty(X)= .

and use:

FullyQualifiedClassName = <name> DotSeparatedList(Ident).


The downside is that we can no longer use the standard set of List
functions. But we don't need them for this case.

The .trim() was essentially a "hack" that I made.
