There is a MWE.

 \documentclass{minimal}
 \usepackage{luatexja}
 
 \ltjsetparameter{kanjiskip=2pt plus .1pt minus 1pt}
 \edef\x{\ltjgetparameter{kanjiskip}}
 \show\x
 
 \ltjsetparameter{kanjiskip=2pt minus 1pt}
 \edef\y{\ltjgetparameter{kanjiskip}}
 \show\y
 
 \stop

The result is

> \x=macro:
->2.0pt plus 0.1pt minus 1.0pt.
l.8 \show\x
         
? 
> \y=macro:
->2.0pt plus 1.0pt.
l.12 \show\y

The \x is fine. But I think tha the value of \y should be 2.0pt minus 1.0pt to correspond to \ltjsetparameter.

It seems that the shrink value of kanjiskip can't be set without a stretch value. I have searched luatexja-en.pdf for detail. But I can't find anything about it. Is this intentional or I miss something?

Thanks. "Fixed" at commit 0275521 (or attached ltj-base.lua.diff).

By the way, in my environment (LuaTeX rev 4917),

 %#!luatex
 \input luatexja.sty
 \ltjsetparameter{kanjiskip={2pt minus 1fil}}
 \edef\y{\ltjgetparameter{kanjiskip}}
 \show\y
 \bye

produces

> \y=macro:
->2.0pt minus 1.0pt.

which should be 2.0pt minus 1.0fil, even the above patch is applied.

But I suspect that there is a bug of LuaTeX, since

%#!luatex
\directlua{
  local s = node.new( node.id('glue_spec') )
  s.width = 65536
  s.stretch_order, s.stretch = 1, 10000
  s.shrink_order, s.shrink = 2, 655360
  tex.setskip(0, s)
}
\message{\the\skip0}
\bye

produces

This is LuaTeX, Version beta-0.79.0 
 restricted \write18 enabled.
(./test.tex 1.0pt plus 0.15259fi minus 10.0pt )
No pages of output.
Transcript written on test.log.

which should be 1.0pt plus 0.15259fi minus 10.0fil.

By the way, in my environment (LuaTeX rev 4917), ... produces {{{

\y=macro:

->2.0pt minus 1.0pt. }}} which should be 2.0pt minus 1.0fil, even the above patch is applied.

That is fixed in LuaTeX rev 4952.
