JavaBBinderHolder* jbh = (JavaBBinderHolder*)
env->GetLongField(obj, gBinderOffsets.mObject);

ALOGV("Java Binder %p: removing ref on holder %p", obj, jbh);
jbh->decStrong((void*)android_os_Binder_init);
} else {
// Encountering an uninitialized binder is harmless. All it means is that
// the Binder was only partially initialized when its finalizer ran and called
// destroy(). The Binder could be partially initialized for several reasons.
// For example, a Binder subclass constructor might have thrown an exception before
// it could delegate to its superclass's constructor. Consequently init() would
// not have been called and the holder pointer would remain NULL.
