NullPointerException or ClassCastException if UPDATE or DELETE is performed on
a diagnostic VTI
-----------------------------------------------------------------------------------------------
Key: DERBY-714
URL: http://issues.apache.org/jira/browse/DERBY-714
Project: Derby
Type: Bug
Components: SQL
Versions: 10.1.1.0, 10.0.2.0
Reporter: Daniel John Debrunner
Assigned to: 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
