Andreas Korneliussen commented on DERBY-1177:
---------------------------------------------
This bug has recently been introduced as part of DERBY-842.

} else if (source instanceof Byte) {
return setObject(targetType, ((Byte) source).byteValue());
} else {
- throw new SqlException(agent_.logWriter_, "Invalid data
conversion:" +
- " Parameter instance " + source +
- " is invalid for requested conversion.");
+ throw new SqlException(agent_.logWriter_,
+ new MessageId (SQLState.LANG_DATA_TYPE_SET_MISMATCH),
+ source.getClass().getName(), Types.getTypeString(targetType));
The new code here causes nullpointerexception when source is NULL.
In addition, when committing the patch for DERBY-842, the output file for
updatableResultSet.out was changed to contain:
- Got expected exception:Invalid data conversion: Parameter instance null is
invalid for requested conversion.
+ Got expected exception:null
Which obvisously is wrong.
The bug was committed as rev. 390536.
