Hi David,
I briefly read over the code that you posted there.
While it should definitely work, it misses an important part of the
JDK Introspector class. Th is class caches all the introspections for
subsequent executions. This makes bean-based reflection very fast.
You version however scans all the methods in the bean for every
property obtained, every time. I can see this as being a major
performance hog.
Best regards,
Geert
