On my Linux test box, sent_body is allways set.
Did there is some default configuration in Apache 2.0 to flush header
automatically ?

Ok, just add some log in mod_jk.c and see :
if (rc > 0) {^M
/* If tomcat returned no body and the status is not OK,^M
let apache handle the error code */^M
jk_log(xconf->log, JK_LOG_INFO, "sent_bodyct=%d status=%d
header_only=%d" , r->sent_bodyct, r->status, r->header_only);
if (!r->sent_bodyct && r->status >= HTTP_BAD_REQUEST) {^M

It's strange but the sent_body is never set, so when HTTP 500 is
encountered, we think we got no BODY from Tomcat and fall back to
Apache 500 error.
Any idea ?
