Spring DefaultContextCache uses hardcoded cache size, instead of the declared property

Affects: master

The documentation for org.springframework.test.context.cache.DefaultContextCache says "configured with a maximum size", there exists a field maxSize, which is set by a constructor parameter, but the contextMap uses a hardcoded size value of 32.

Comment From: snicoll

The value is the initial capacity of the cache, not its max size.
