 Description   

The PreparedStatement#executeBatch() functionality does not properly handle interrupts when the thread is interrupted while waiting on a response from the server.

The InterruptedException is currently being swallowed in AbstractMultiSend instead of being propagated back to the caller.

This manifested as a NullPointerException:

java.lang.NullPointerException: null
 
	at org.mariadb.jdbc.MariaDbServerPreparedStatement.executeBatch(MariaDbServerPreparedStatement.java:276) ~[mariadb-java-client-1.5.7.jar:na]
 
...snip...

The NPE is due a race condition. The thread was interrupted so it is returning before the results are available
