Affects: 5.2.6.RELEASE

The following scenario triggers deadlock:

• Run non-main threads that invoke a method of @Repository bean in @PostConstruct block.
• The method throws an exception.
• Wait the non-main threads to be completed in @PostConstruct block.

This is a sample project to demonstrate it: https://github.com/izeye/spring-boot-throwaway-branches/tree/post-construct-deadlock

Just running it will trigger deadlock.

I'm not sure if this is unsupported usage or bug.
