> Right now the ORC JNI bridge uses some custom buffer passing which only seems to handle primitive arrays correctly (child array buffers and dictionaries are not considered):
> https://github.com/apache/arrow/blob/master/cpp/src/jni/orc/jni_wrapper.cpp#L263-L265
> Instead, it should use the C data interface, which is now implemented in Java.
