NullPointerException for interface based projection

[makigumo]

Hello, after updating to the latest spring boot release 2.6.3 I'm met with the NullPointerException below.

The following change (#2363 8cd1388) seems to be the cause.

I'm using a simple recursive interface based projection with a query method, similar to Example 81 in https://docs.spring.io/spring-data/jpa/docs/current/reference/html/#projections, which has worked until now.

I got the same error after upgrading to Spring boot 2.6.3.
