This commit introduces a test which verifies how many times the
matches() method of a StaticMethodMatcherPointcut is invoked during
ApplicationContext startup as well as during actual method invocations
via the advice chain, which also indirectly tests the behavior of the
equals() implementation in AdvisedSupport.MethodCacheKey.
In addition, this commit revises BeanFactoryTransactionTests to assert
that a transaction is started for the setAge() method.
