Subject Re: @Singleton @Lock(READ) to resolve, Could not instantiate converter ...
Date Sun, 14 Apr 2013 01:41:33 GMT
Maybe could be a request for Rommain, i remember that tomee logs some info
about ejb but im not sure what exactly.

By the way i saw that you return null in your converters catch "statement".
Why dont throw a converterexception?
