-----------------------------------------
Summary: [Java] shade flatbuffer dependency
Key: ARROW-5579
URL: https://issues.apache.org/jira/browse/ARROW-5579
Project: Apache Arrow
Issue Type: Task
Components: Java
Reporter: Pindikura Ravindra
Reported in a [github issue|[https://github.com/apache/arrow/issues/4489]]
After some [discussion|https://github.com/google/flatbuffers/issues/5368] with
the Flatbuffers maintainer, it appears that FB generated code is not guaranteed
to be compatible with _any other_ version of the runtime library other than the
exact same version of the flatc used to compile it.
This makes depending on flatbuffers in a library (like arrow) quite risky, as
if an app depends on any other version of FB, either directly or transitively,
it's likely the versions will clash at some point and you'll see undefined
behaviour at runtime.
Shading the dependency looks to me the best way to avoid this.
