Description

The struct type (or RelRecordType) is hard coded NOT nullable, which lead exception thrown when invoking:

RexBuilder.makeLiteral(null, structType);

The exception looks like following:

java.lang.IllegalArgumentException
        at com.google.common.base.Preconditions.checkArgument(Preconditions.java:108)
        at org.apache.calcite.rex.RexLiteral.<init>(RexLiteral.java:217)
