Jesús Pérez Alcaide (ISBAN) commented on MYFACES-3549:
------------------------------------------------------
Thank you Leonardo for your valuable comments.
I spent the whole morning looking for information about the final and volatile
keywords. I think making _readMethodRef volatile could reduce the number of
calls to _descriptor.getReadMethod() when the soft reference is cleared, but
this only occurred when the server is about to run out of memory.
In this scenario it is uncertain whether the server is able to recover enough
memory to continue execution, so I don't know whether it is worthwhile to
optimize the code for that delicate situation. I think it is reasonable to
optimize the typical case, and that's what I intend with my proposal.

> I would like to propose an alternative solution to bugs MYFACES-3262 and
> MYFACES-3510, which consists in rollback the changes made in MYFACES-3510 and
> modify the solution given in MYFACES-3262 by adding a soft reference to the
> methods held in the class _PropertyDescriptorHolder.
> This alternative solution fixes MYFACES-3262 and avoids the performance loss
> caused by MYFACES-3510.
