>      Project: Derby
>         Type: Bug
>   Components: SQL
>     Versions: 10.1.1.0, 10.0.2.0
>     Reporter: Daniel John Debrunner
>     Assignee: Daniel John Debrunner
>     Priority: Trivial
>      Fix For: 10.2.0.0

>
> UPDATE and DELETE statements on read-only vtis will hit NullPointerException in insane mode, and ClassCastException in sane mode.
> ij> delete from new org.apache.derby.diag.TransactionTable();
> ERROR XJ001: Java exception: ': java.lang.NullPointerException'.
> While these statements make no sense, a more graceful error should be returned, especially as in insane mode this causes the engine to shutdown. Code already exists to detect this situation but is not being called.
> Found through adding negative tests for DERBY-571
