7.0.7 - DatastoreServiceMethodInvokingFactoryBean - FactoryBean threw exception from getObjectType

[zyro23]

Task List

• Steps to reproduce provided
• Stacktrace (if present) provided
• Example that reproduces the problem uploaded to Github
• Full description of the issue provided (see below)

Steps to Reproduce

1. run referenced sample app
2. see errors/stacktrace

Expected Behaviour

injection should work, sample app should start

Actual Behaviour

depending on how/where a data service is autowired, spring may inspect the data service bean before it is initialized (e.g. @Autowired into a BeanPostProcessor, see sample app).

in this case, DatastoreServiceMethodInvokingFactoryBean.getObjectType() throws an exception which violates the FactoryBean.getObjectType contract:
