Mike Matrigali commented on DERBY-6391:
---------------------------------------
note, do not backport any such change to 10.10 or previous release. It will
not work.
> remove unneeded object creation in newException() calls in releases > 10.10

> Key: DERBY-6391
> URL: https://issues.apache.org/jira/browse/DERBY-6391
> Project: Derby
> Issue Type: Improvement
> Affects Versions: 10.11.0.0
> Reporter: Mike Matrigali
> Labels: derby_backport_reject_10_10
>
> In releases after 10.10 the code has been converted to use new
> java language features. One of the benefits I just noticed is that
> arguments to StandardException.newException() no longer have
> to be Objects. I believe this is due to reimplementation using varargs.
> As an example old code use to have to be written as:
> throw StandardException.newException(
> SQLState.FILE_BAD_CHECKSUM,
> id,
> new Long(checksum.getValue()),
> new Long(onDiskChecksum),
> pagedataToHexDump(pageData));
> The only reason for the new Long() calls was to make them Objects so
> that the call would match up to a hard coded N Object arg version of
> the newException call. I believe these conversions to Objects are no
> longer needed (but formatting of the args might change).
> There may be code size savings to be had by doing this code
> rototil.
> Anyone see a downside to changing the code in this way?
