Andrus Adamchik closed CAY-1998.
--------------------------------
Resolution: Fixed
Fix Version/s: 4.0.M3
Ended up with a solution precompiling property path to a linked list of
unresolved Accessors. When each object is evaluated, each path component has to
look up a "segment" Accessor in the cache, and then call it to get the value.
Perhaps we'll be able to build something more efficient with java 7
MethodHandles (as those do not require us to know upfront the type of the
target object for evaluation).
Still need to run performance tests.

>
> PropertyUtils are very slow (especially in multi-threaded apps) when working
> with POJOs as every call to 'getProperty' results in java.beans.Introspector
> call , that is synchronized and slow. Hoping that replacing this with an
> internal cache of accessors per path would improve the situation.
