Shared state in ByteBuddy basic proxies leads to intermittently broken persistence

Description

When the ByteBuddy BasicProxyFactoryImpl is used to generate proxies, the proxies it generates share a common ProxyConfiguration.Interceptor - which is used to hold the bean state. This then breaks during concurrent use as parallel threads compete for the state.

Proposed solution is to instantiate a new interceptor per innovation of BasicProxyFactoryImpl. getProxy()

A PR has been raised as per this proposal.

Ignore the above comment. I added a test to ByteBuddyBasicProxyFactoryTest to demonstrate the issue and fix.

I’ve created a PR with a fix, but an as yet to be completed test. Inlined from the PR:

I’ll keep plugging away at the test, but any pointers would be received with gratitude!
