Hi,

  I found a bug in VariantTransform::setReturnValue(jboolean in,  VARIANT& returnValue).
 
  I used comJava in a VB app and was accessing an java.util.Iterator object. The value returned by Iterator.next() when there is no more eleements is NULL causing the Variant value not to be set. I some environment (VB IDE, WSH/VBScriptthis) it means VARIANT_FALSE. However, in others (VB app out of IDE) it means VARIANT_TRUE. Though, the following fix:
 
void VariantTransform::setReturnValue(jboolean in,  VARIANT& returnValue)
{
    checkForException();
    returnValue.vt = VT_BOOL;
    if (in != NULL) {
        if (in == JNI_TRUE)
            returnValue.boolVal = VARIANT_TRUE;
        else
            returnValue.boolVal = VARIANT_FALSE;
    }
  else {
    returnValue.boolVal = VARIANT_FALSE;
  }
}
