Works for me (using openjdk 11.0.1).

Your problem may be that you're running the script using load,
or using the -f command-line flag.  That reads, compiles, and evaluates
each line one-by-one which is undesirable for a number of reasons.
For one it hurts various optimizations and requires more reflection.

Instead run the script directly from the command line:

     $ kawa my-script.scm

(without using the -f option).

If using the REPL, you can use require instead of load:

     $ kawa
     #|kawa:3|# (require  "my-script.scm")

Note that "load" is a procedure that reads the file line-by-line,
while "require" is syntax (a macro) that reads the file at "compile-time".
     
It will also work better (no warnings) if you stick to using
the CLASS_NAME:METHOD_NAME syntax for static methods.  For instance methods
we prefer INSTANCE:METHOD_NAME.

Specifically, replace the last two lines by:

     (define response (client:send request body-handler))
     (display (response:body))
