> In some cases, e.g. JVM_ARGS does not match the java executable version that
> pyflink uses when launching py4j gateway server, there'll be only a general
> message "Exception: Java gateway process exited before sending its port
> number". It would be easier to investigate the error cause if we expose
> stderr from java process.
