> retry-test and multi-retry-test fails flakily when run with 
> {code}
> buck test --all --no-results-cache
> {code}
> or when run in a loop:
> {code}
> for i in `seq 1 10`; do buck test --no-results-cache core:retry-test || break 1; done
> {code}
> The problem seems to be within the JNI internals and usually happens at the create table
method call. I was not able to inspect much, but the comments in our mini-cluster indicate
that we may need to use global references instead of local ones. I suspect the problem happens
when there is a GC run for the test since the failure happens usually after some time (but
almost always in create table method). 
> [~ted_yu] do you mind taking a look at this.
