      Description

      Inserting into a global temporary table (GTT) while selecting data from a VTI fails with a NullPointerException:

      Caused by: java.lang.NullPointerException
      at org.apache.derby.impl.sql.execute.WriteCursorConstantAction.getEmptyHeapRow(WriteCursorConstantAction.java:324)
      at org.apache.derby.impl.sql.execute.InsertResultSet.bulkInsertCore(InsertResultSet.java:1209)
      at org.apache.derby.impl.sql.execute.InsertResultSet.open(InsertResultSet.java:466)
      at org.apache.derby.impl.sql.GenericPreparedStatement.executeStmt(GenericPreparedStatement.java:443)
      at org.apache.derby.impl.sql.GenericPreparedStatement.execute(GenericPreparedStatement.java:324)
      at org.apache.derby.impl.jdbc.EmbedStatement.executeStatement(EmbedStatement.java:1242)
      ... 6 more

      Investigation exposed the fact that bulk insert doesn't support a GTT as the target, and further that Derby enables bulk insert when the source is a VTI.
