> Noticed it in 10.2, but also reproduces with 10.1.
> Set the following property and then try creating a schema as follows:

> ij version 10.2

> ij> create schema mysam1;
> ERROR XJ001: Java exception: ': java.lang.NullPointerException'.
> I suspect the problem is because DDLStatementNode.java expects an object name that most
DDL statements set, but not CreateSchemaNode.java.
