[seam-dev] Impact of the change of scope (EVENT to SESSION) of the EjbSynchronizations SFSB component?

[Marek Novotny]

Sorry for my late response, but I was busy by other issues. Anyway I
rollbacked the change today. 

The main reason is performance impact, which was shown in stress tests,
which Jozef processed on my request and I thank him for the evidence.

If you have any idea on fixing the JBSEAM-4542, I will welcome any help.
