> Compilation of our rules are taking a long time.
> During profiling, one bottleneck that appears is excessive Class.forName lookups.
> CompositeClassLoader caches class that are found successfully, but does not cache those that were not found.
> Mvel tries to lookup "non-existent" classes a lot during compilation.
> Caching these ClassNotFounds should speed up the compilation.
> This change alone brought down our compilation time from 163854ms to 47312ms
> on my dev box.
