Scoped beans force all AOP proxies to CGLib proxies. Setting <aop:config proxy-target-class="false"> doesn't change this behaviour. [SPR-3071]

Luciano Montebove opened SPR-3071 and commented

When in an applicationContext configuration file is added a scoped bean as for example :
<bean id="id" class="com.Test"
scope="session">
<aop:scoped-proxy />
</bean>
All AOP proxies even not involved with this bean will be CGLib proxies.
Trying to force JDK proxies with <aop:config proxy-target-class="false"> doesn't produce any effect.

Thanks for raising this point! While a scoped proxy does require the target bean to expose the full target class, it's certainly going too far to enforce target class proxying for all beans in the context. Therefore, I've reimplemented this to selectively enforce target class proxying for the affected target bean. Furthermore, aop:scoped-proxy now has a "proxy-target-class" attribute, with default value "true"; turn this to "false" to define a scoped proxy based on interfaces only (a capability that the underlying ScopedProxyFactoryBean already had).
