--- Comment #11 from Timcesq <ti_m...@poczta.fm> ---
I used a debugger to locate the crash address in the source code. It looks like
the crash occurs inside the function "Java_org_apache_tomcat_jni_Poll_poll",
specifically inside the following block:
for (i = 0; i < num; i++) {
tcn_socket_t *s = (tcn_socket_t *)fd->client_data;
p->set[i*2+0] = (jlong)(fd->rtnevents);
p->set[i*2+1] = P2J(s);
if (remove) {
apr_pollset_remove(p->pollset, fd);
APR_RING_REMOVE(s->pe, link);
APR_RING_INSERT_TAIL(&p->dead_ring, s->pe, tcn_pfde_t, link);
s->pe = NULL;
p->nelts--;
#ifdef TCN_DO_STATISTICS
p->sp_removed++;
#endif
}
else {
/* Update last active with the current time
* after the poll call.
*/
s->last_active = now;
}
fd ++;
}
The crash address suggests that a read of the "s->pe" variable inside the
"if(remove)" block fails (the variable is null).
