Introduction of contrib-agent causes runtime failure

[blt-gw]

Please answer these questions before submitting a bug report.

What version of OpenCensus are you using?

0.23.0

What JVM are you using (java -version)?

java version "1.8.0_221"
Java(TM) SE Runtime Environment (build 1.8.0_221-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.221-b11, mixed mode)

What did you do?

If possible, provide a recipe for reproducing the error.

I've introduced the use of contrib-agent, by adding the javagent flags to my program args as suggested in the readme here.

What did you expect to see?

While I have been able to successfully emit trace fragments no traces have been correlated correctly by their trace id. I expected to see normal traffic patterns against my server with properly correlated traces being emitted.

What did you see instead?

I did see properly correlated traces but I also saw a server killing exception in my logs:

Additional context

I build under bazel. Not sure if that's relevant.
