Some more info that i just stumbled on:
This doesn't actually happen on master, or on release-1.4 for that matter.
For FLINK-7419 we're adding another relocation pass to flink-dist for
jackson, and this appears to trigger the error.
master: succeeds
+ relocation in flink-dist: fails, _always_
+ asm dependency bump: succeeds---
