> 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?
