>             Project: iBatis for Java

> Putting that as major even though it is trivial since it affects migration and I guess users would scratch their head a bit more than necessary.
> Upgrade from 2.1.7 which had a sqlmap config with settings:

>             cacheModelsEnabled="true"
>             enhancementEnabled="false"
>             lazyLoadingEnabled="false"
>             maxRequests="512"
>             maxSessions="128"
>             maxTransactions="32"

>             errorTracingEnabled="true"
>             />
> {noformat}
> And got an error message that led me scratching my head for a while until I digged in the source code to figure out it was no more used. But the message is terribly misleading ( 'Attribute "maxRequests" must be declared for element type "settings".)
> Removing maxRequests, maxSession, maxTransactions from the settings solves the problem.
