      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
