jni exception log excerpt

cpp interface for throwing exceptions back thru JNI to java/android layer...

    jobject buffer, jint bufsize)
{
  FLACStreamEncoder * encoder = get_encoder(env, obj);

  if (NULL == encoder) {

/**
 * Throws the given exception/message
 **/

  // If cls is NULL, an exception has already been thrown
  if (NULL != cls) {
    env->ThrowNew(cls, msg);
    // Ignore return value of ThrowNew... all we could reasonably do is try and
    // throw another exception, after all.
