Name: jl125535 Date: 07/12/2004


FULL PRODUCT VERSION :
java version "1.5.0-beta2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b51)
Java HotSpot(TM) Client VM (build 1.5.0-beta2-b51, mixed mode, sharing)


ADDITIONAL OS VERSION INFORMATION :
Linux willow.uwyn.office 2.6.7-gentoo-r6 #1 Tue Jun 29 12:05:28 CEST 2004 i686 Intel(R) Pentium(R) 4 CPU 2.00GHz GenuineIntel GNU/Linux

A DESCRIPTION OF THE PROBLEM :
The JDBC ResultSet interface got generified, more specifically the getObject(int, Map) and getObject(String, Map) methods. However, the new signatures getObject(int, Map<String, Class<?>>) and getObject(String, Map<String, Class<?>>) are not backwards compatible with already implemented ResultSets. The compiler complains that the ResultSet implementing class should be abstract since the new method signatures aren't implemented. So this leaves you with the burden of having to maintain two seperate sources files. One for JDK 1.4 and one for 5.0.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile any ResultSet implementing class from 1.4 with 5.0.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Successful compilation.
ACTUAL -
Compiler error:
com.uwyn.rife.database.DbResultSet is not abstract and does not override abstract method getObject(java.lang.String,java.util.Map<java.lang.String,java.lang.Class<?>>) in java.sql.ResultSet


ERROR MESSAGES/STACK TRACES THAT OCCUR :
Compiler error:
com.uwyn.rife.database.DbResultSet is not abstract and does not override abstract method getObject(java.lang.String,java.util.Map<java.lang.String,java.lang.Class<?>>) in java.sql.ResultSet


REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Use seperate source files for JDK 1.4 and 5.0 with only the getObject method signatures being different.
