Optimize the initialization of hashmap

Comment From: sbrannen

Hi @springmonster,

Nice GitHub handle. 😉

Congratulations on submitting your first PR for the Spring Framework. 👍

Normally we don't bother with simplifying such declarations in test fixtures; however, since this is your first contribution, I'll go ahead and merge this one in.

Thanks
