/**
 * Test that by-type bean lookup caching is working effectively by searching for a
 * bean of type B 10K times within a container having 1K additional beans of type A.
 * Prior to by-type caching, each bean lookup would traverse the entire container
 * (all 1001 beans), performing expensive assignability checks, etc. Now these
 * operations are necessary only once, providing a dramatic performance improvement.
 * On load-free modern hardware (e.g. an 8-core MPB), this method should complete well
 * under the 1000 ms timeout, usually ~= 300ms. With caching removed and on the same
 * hardware the method will take ~13000 ms. See SPR-6870.
