It does seem to work ok with "root-relative" filenames.  I.e. if class file
kawa/lib/vectors.class contains:

Attribute "SourceFile", length:2, #510="strings.scm"
Attribute "SourceDebugExtension", length:90
SMAP
strings.scm
Scheme
*S Scheme
*F
+ 1 strings.scm
kawa/lib/strings.scm
*L
1#1,122:1
*E

In that case Eclipse can map the stack trace to the source file.

Here is a nice screenshot:

Note the vectors.scm line in the track-trace.  I clicked on it,
and it brought up the nice syntax-colored source code.
Note is also the local variable 'vec' in the Variables display,
with the contents printed (using toString).

Stepping works too.  What doesn't work is setting a breakpoint
from the Scheme window, but this is looking promising.
