From a 2d-dev list posting :

I notice that there is a native method freeTransform() in LCMS.java, but
LCMS.c doesn't have an implementation for that. There is only
LCMS_freeTransform(), which of course isn't a JNI method. It could
easily be implemented like this:

JNIEXPORT void JNICALL
Java_sun_java2d_cmm_lcms_LCMS_freeTransform(JNIEnv* env, jclass cls,
jlong id) {
  LCMS_freeTransform(env, id);
}

Wondering, why this never showed up anywhere, I digged a little deeper
an looked around for possible callers of freeTransform(), but found
none. Considering this, I think this must be a stale method maybe left
from some earlier experiments and could be removed now. Is this correct?
In this case, I would propose to remove the native method declaration.
