Knut Anders Hatlen commented on DERBY-3041:
-------------------------------------------
utilMain/utilMain14 have workarounds for problems in WebLogic 4.5
(AbstractMethodError because JDBC 2.0 was not implemented). Most of the
workarounds for this problem were removed in this commit:
------------------------------------------------------------------------
r426887 | djd | 2006-07-30 16:40:08 +0200 (su, 30 jul 2006) | 1 line
Minor cleanup in ij code, make methods non-public and remove an un-required
method.
------------------------------------------------------------------------
I assume it is OK to remove the workarounds that were forgotten in the previous
clean-up. If WebLogic 4.5 didn't implement JDBC 2.0, I doubt that it is able to
load classes compiled for Java 1.4 anyway.

> The classes utilMain and utilMain14 contain utility methods for manipulating
> the holdability of a connection or a statement. There is one implementation
> for JDBC 2.0 JVMs and one implementation for JDBC 3.0 JVMs. Since Derby now
> only supports JVMs which support JDBC 3.0 (or JSR-169 which is a subset of
> JDBC 3.0), we could move code from utilMain14 to utilMain and delete
> utilMain14. The class Main14 behaves identically to the class Main, except
> that it returns utilMain14 instances, so once the utilMain14 class is
> removed, Main14 can be removed as well.
