YamlProcessor subclasses can no longer instantiate StrictMapAppenderConstructor [SPR-13504]

[spring-projects-issues]

Andy Wilkinson opened SPR-13504 and commented

Spring Boot fails to compile against the latest 4.2.2 snapshots due to the removal of StrictMapAppenderConstructor's public constructor in 667fc7e4.

We could work around the problem in Boot by subclassing StrictMapAppenderConstructor but I would prefer not to.

Oops, I thought that was a redundant declaration... It's back now.

I wonder why we haven't discovered it earlier though? That commit was almost three weeks old!

Boot was not on SPR snapshot until recently.
