Description

I got the following NPE trying to use Drill with JDBC:

java.lang.NullPointerException
at org.apache.drill.exec.vector.accessor.AbstractSqlAccessor.getString(AbstractSqlAccessor.java:102)
at org.apache.drill.exec.vector.accessor.NullableFloat8Accessor.getString(NullableFloat8Accessor.java:87)
at org.apache.drill.jdbc.AvaticaDrillSqlAccessor.getString(AvaticaDrillSqlAccessor.java:66)
at net.hydromatic.avatica.AvaticaResultSet.getString(AvaticaResultSet.java:205)

It was caused by NULL value stored as DOUBLE.
