I'm working with Alan Ruttenberg to port LSW from the old version of JSS to the JSS that is now part of abcl-contrib.
We've run into the following bug when using with-constant-signature:
; these first two work fine: (#"substring" "some string" 2 4) ; "me" (#"substring" "some string" 2) ; "me string"
; and so does this (with-constant-signature ((substring "substring")) (substring "some string" 2 4)) ; "me"
; but this breaks: (with-constant-signature ((substring "substring")) (substring "some string" 2)) ; Wrong number of arguments for public java.lang.String java.lang.String.substring(int,int): expected 2, got 1 ; [Condition of type PROGRAM-ERROR]
A problem seems to be in jss::invoke-find-method, which is finding the two argument version of java.lang.String.substring no matter how many arguments its given:
(jss::invoke-find-method "substring" "this is a string" '(1)) ; should return the java.lang.String.substring method with one int arg ; #<method public java.lang.String java.lang.String.substring(int,int)>
(jss::invoke-find-method "substring" "this is a string" '(1 2) ) ; #<method public java.lang.String java.lang.String.substring(int,int)>
(jss::invoke-find-method "substring" "this is a string" '(1 2 3 4 5 6 7 8) ) ; should be an error ; #<method public java.lang.String java.lang.String.substring(int,int)>
