Switching muzzle to target spring-tx rather than spring-data (which is logical given the instrumentation point)
Also added extraDependency on aopalliance
This restricts the support the Spring 2.5 when spring-tx & spring-aop using aopalliance were introduced.
After experimenting with RepositorySupport$QueryExecutorMethodInterceptor switched to TransactionInterceptor.
QueryExecutorMethodInterceptor was too narrowly scoped and didn't capture the UPDATE or DELETE statement. TransactionInterceptor captures everything, but is still a bit more broadly applicable than I'd like.
