DiscoveryIntegrationTest intermittently fails

[jtraglia]

Description

As part of the CI build, this test (shouldRecoverAfterErrorWhileDecodingInboundMessage) will intermittently fail. If you push another commit to the PR, half of the time it will succeed. I've been unable to reproduce this failure locally. There's already a 30 second timeout (in waitFor), so I don't think it's a slow test that's taking too long.

DiscoveryIntegrationTest > shouldRecoverAfterErrorWhileDecodingInboundMessage() FAILED
    java.util.concurrent.TimeoutException at DiscoveryIntegrationTest.java:369
