-----------------------------------

             Summary: NPE in getStringFromVarCharHolder(NullableVarCharHolder) 
                 Key: DRILL-7677
                 URL: https://issues.apache.org/jira/browse/DRILL-7677
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Niels Basjes


Assume you have a function ([like this one|https://github.com/apache/drill/blob/master/contrib/udfs/src/main/java/org/apache/drill/exec/udfs/UserAgentFunctions.java#L110]) that has
{code:java}
@Param
NullableVarCharHolder input;
{code}
and in the {code:java}eval(){code} function you do
{code:java}String inputString = org.apache.drill.exec.expr.fn.impl.StringFunctionHelpers.getStringFromVarCharHolder(input);code}

When this function is called with the input actually being null the 'input' parameter is an instance of NullableVarCharHolder where isSet is 0 and buffer is null.

The buffer being null causes an NPE in the call to getStringFromVarCharHolder(NullableVarCharHolder)
