I tried this with scheme-program-name as
 "java -cp /home/hoehle/archive/kawa-1.7.jar kawa.repl")) -- no difference:
#|kawa:1|# (try-catch (catch #t (lambda () (+ "abc" 1)) (lambda _ #f)) (exc <java.lang.Exception> (display 6)))

What I posted (myenv-kawa.scm) to the mailing lists last year or so (the attached file is also found in the Kawa mailing list archives) was what I used for SXML-tree-trans and SXML-to-HTML. I didn't use SSAX last year, only pre-post-order and transformations: no parsing of XML.
Trying out the current CVS SSAX now, I'm under the impression that it would not work with Kawa-1.6.98 (some errors I reported, others I did not even bother to report, for they are gone in 1.7), nor would presumably last year's SSAX code work.

I tried it out now: no improvement!

On a Linux box this time, featuring a slightly newer Java version
java version "1.3.1_04"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_04-b02)
Java HotSpot(TM) Client VM (build 1.3.1_04-b02, mixed mode)

I obtain the dreaded NullPointerExc on the previously mentioned expression containing these test cases:
  (test "]]>" '())
  (test "abcd]]>" '("abcd" ""))
  (test "abcd]]]>" '("abcd" "" "]" ""))

I used
M-x run-kawa then from your file test-kawa.scm:
(load "lib/myenv.scm")
(load "lib/myenv-kawa.scm")
(load "lib/srfi-13-local.scm")
;(load "lib/srfi-12.scm")
(load "lib/catch-error.scm")
(load "lib/char-encoding.scm")
(load "lib/input-parse.scm")
;(load "lib/util.scm")
(load "lib/SSAX.scm")

If from there, I evaluate further definitions from SSAX.scm interactively I get until (define ssax:read-attributes ...
which also errors out.

How comes your code/archive works for you!? what else could be different
