Hello, I am now getting this error since adding usage of BigQuery Storage
API when reading from a table using `.withMethod(Method.DIRECT_READ)` using
beam 2.21.0. The error stack trace I get is similar to the one above:
`Error message from worker: java.lang.IllegalStateException: BEAM-9399:

Please let me know. Thank you.

> When an exception is encountered in DataflowWorkerLoggingHandler the
> ErrorManager is used to log the exception. ErrorManager uses System.err
> which is overridden to be a PrintStream that writes back into
> DataflowWorkerLoggingHandler.
> This has the lock ordering DataflowWorkerLoggingHandler -> PrintStream.
> Other logging of System.err has the inverse lock ordering
> PrintStream->DataflowWorkerLoggingHandler so there is potential for deadlock.
> This is one known cause of the inversion, but any other System.err logs from
> inside DataflowWorkerLoggingHandler could cause the same issue.
> Proposed fix is to address low-hanging fruit of having ErrorManager output to
> the original System.err. A full fix would be to improve our override of
> System.err to a PrintStream that can detect the locking inversion or possibly
> we could use the PrintStream mutex in both cases.
