[jamming] :E broken?

[Weber, Daniel]

Hi all,

given these lines of jam code

   empty = ;
   notEmpty = value ;
   
   echo 111 $(notEmpty) 111 ;
   echo 222 $(empty) 222 ;
   echo 333 $(notEmpty:E=$(empty)) 333 ;
   echo 444 $(notEmpty:E=$(empty:E=)) 444 ;
   
I'd expect the following output:

   111 value 111 
   222 222 
   333 value 333 
   444 value 444 

the :E on line 3 does not have to be evaluated since 
$(notEmpty) is not empty.

But jam taught me otherwise:

   111 value 111 
   222 222 
   333 333 
   444 value 444 

Am I missing something? Has anyone else encountered this?
If it really is a bug, maybe someone out there already 
fixed it?

We are using jam 2.5.

Kind Regards,
Daniel
