Ok I understand more or less now.
This is what I came up with instead:
(deffunction split-md5-line (?line )
(bind ?s (new String ?line ))
(bind ?items (?s split "[ ]+" ) )
(return ?items)
)

Subject: Re: JESS: jess: (length$ (explode$ "679196dc49add8e88a07bd9fd34ec2f7 /a/b")) versus Jess> (length$ (explode$ "679196dc49add8e88a07bd9fd34ec2f7 .a/b"))
"/" is a special character in Jess. In particular, two "/" characters delimit a regular expression, which can't actually be used the way you're "using" it. That symbol consisting of a single double-quote is the (admittedly strange) way that Jess has interpreted what you've asked it to do.
In any case, recent versions of the manual take some pains to mention that file paths must absolutely be written as quoted strings in Jess; i.e., this does what you want:
Jess> (explode$ "679196dc49add8e88a07bd9fd34ec2f7 \"/a/b\""))
(679196dc49add8e88a07bd9fd34ec2f7 "/a/b")
