Rick Hillegas updated DERBY-4459:
---------------------------------
Attachment: derby-4459-01-aa-disableOptimization.diff
Attaching derby-4459-01-aa-disableOptimization.diff. This disables the same
over-eager optimization which led to DERBY-1030.
For more context, please see DERBY-1030. This is another case of that
optimization being applied too liberally. This patch disables that optimization
when the bind() phase has determined that an argument needs to be cast to a
primitive in order to match the selected method. Running tests now.
Touches the following files:
-------------
M java/engine/org/apache/derby/impl/sql/compile/StaticMethodCallNode.java
Disables the optimization.
-------------
M
java/testing/org/apache/derbyTesting/functionTests/tests/lang/RoutineTest.java
Adds a test case.
> Verification error at execute-time when an outer function which takes a
> primitive arg is wrapped around an inner function which returns the
> corresponding Java wrapper object

> Affects Versions: 10.4.2.1, 10.5.3.1, 10.6.1.0

> An insane Derby raises a verification error when trying to run the following
> query:
> values( negateInt( getNullInt() ) );
> where negateInt() takes a primitive int argument and getNullInt() returns an
> Integer.
> Sane Derby raises an assertion. The same test case, run against 10.3.3.1,
> also fails but raises a more graceful compile-time exception.
