Thanks for the update, Bryan, but the problem still persists. In my setup (Xen hosts):  Domain.getSchedulerParameters() still raises a NPE.

In libvirt.h, _virSchedParameter is defined as follows using a union for the value:

struct _virSchedParameter {
    char field[VIR_DOMAIN_SCHED_FIELD_LENGTH];  /* parameter name */
    int type;   /* parameter type */
    union {
        int i;                          /* data for integer case */
        unsigned int ui;        /* data for unsigned integer case */
        long long int l;        /* data for long long integer case */
        unsigned long long int ul;      /* data for unsigned long long integer case */
        double d;       /* data for double case */
        char b;         /* data for char case */
    } value; /* parameter value */

I believe the Java mapping of virSchedParameterValue should be a Union instead of a Structure:
public class virSchedParameterValue extends Union {...}
