Rick Hillegas updated DERBY-5488:
---------------------------------
Attachment: derby-5488-02-aa-fixBigInteger.diff
Attaching derby-5488-02-aa-fixBigInteger.diff. This patch corrects the behavior
of setObject( int, BigInteger ). I will run tests.
The overflow/underflow/truncation behavior of setObject() is not clearly
documented by the JDBC spec. Lance Andersen thinks that this might be addressed
in JDBC 4.2, the next rev of the spec which will accompany Java 8.
In the meantime, I have let the following principles guide the revised
implementation of setObject( int, BigInteger ):
1) Overflow/underflow/truncation should behave as it does for other numeric
objects.
2) BigInteger should not be less capable than the corresponding BigDecimal for
the same integer value.
Touches the following files:
----------
M java/engine/org/apache/derby/impl/jdbc/EmbedPreparedStatement20.java
M java/engine/org/apache/derby/impl/jdbc/EmbedPreparedStatement.java
Fix for embedded JDBC driver.
----------
M java/client/org/apache/derby/client/am/CrossConverters.java
M java/client/org/apache/derby/client/am/PreparedStatement.java
Fix for network JDBC driver.
----------

java/testing/org/apache/derbyTesting/functionTests/tests/jdbcapi/ParameterMappingTest.java
Additional test case to verify overflow/underflow/truncation behavior.
> Add remaining JDBC 4.1 bits which did not appear in the Java 7 javadoc.
