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.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.
