beam_PreCommit_JavaPortabilityApi_Cron fails due to a timeout

Looks like last three runs failed (so probably perma red).

For example,

https://builds.apache.org/job/beam_PreCommit_JavaPortabilityApi_Cron/26/console

Scott, looks like this first failed for your following commit. But not 100% sure if this is the reason.
