Precise check should be to validate if the given interfaces == the

Hi Mandy,
I will try to profile this approach as a post-validation and let you
know the results.
Hi Mandy,
Here's the modified webrev using optimized String-based sub-keys and
pos-validation of proxyClass using proxyClass.getInterfaces():

The benchmark results are the following:
Summary (4 Cores x 2 Threads i7 CPU):
WeakCache+
ns/op Strings key+
Test Threads Original getIntfcs() post-valid.

... not that bad, but not so great either, compared to Weakly
