 Description   

A NullPointerException occurs in AbstractMultiSend when useBatchMultiSend is false. This happens on line 241 of AstractMultiSend.java On "AbstractQueryProtocol.readScheduler.execute(futureReadTask);"

The reason is that readScheduler is not set in AbstractQueryProtocol constructor:

if (options.useBatchMultiSend && readScheduler == null) {
synchronized (AbstractQueryProtocol.class) {
if (readScheduler == null)

{ readScheduler = SchedulerServiceProviderHolder.getBulkScheduler(); }

}
}

It looks as if there is no code to do synchronous batch in "executeBatchStandard". We have implemented a synchronous version, and are willing to contribute.

Is the above issue is resolved? we used aurora to execute the batch statements and getting the below exception.
Caused by: java.lang.NullPointerException: null
at org.mariadb.jdbc.internal.protocol.AbstractMultiSend.executeBatchStandard(AbstractMultiSend.java:241) ~[mariadb-java-client-1.5.9.jar:na]

when will we expect the fix.

Thanks
