Shane Bryzak commented on JBSEAM-2917:
--------------------------------------

This is probably just one of many performance improvements that we can potentially make, we could probably backport it to 2.0.2 (although the code will be different as these methods have changed).  I think we should be focused on a more formal profiling and performance effort for 2.1.0, rather than any 'here and there' minor fixes we can squeeze into 2.0.2.

> Seam.getEjbDescriptor re-initializes its cache of descriptors every time it fails to find a given class.  This method is getting called for every non-injected field of a conversational component, on every invocation of a method in that component.  In my case, getEjbDescriptor  was eating up an average of 20% of page time before the attached patch.
