Unpooled SLSB semantics
-----------------------
Key: EJBTHREE-73
URL: http://jira.jboss.com/jira/browse/EJBTHREE-73
Project: EJB 3.0
Type: Feature Request
Versions: Preview 5, Preview 4
Reporter: Andrew Oliver
Assigned to: Bill Burke
EJB3 should allow optional servlet-style thread model semantics for stateless
session beans. Meaning, rarely is object pooling of SLSBs of any real
advantage aside from contraining resources which is usually better done in
places like thread pools and isn't commonly made use of to constrain individual
application components in practice.
basically a "@TheadSafeSLSB" or some like tag would mark that it was safe to
send all threads to the a single instance of an SLSB. You'd follow similar
practices that you use for Servlets which you almost have to do anyhow for
SLSBs. You'd no longer be granted an object lock for the scope method
invocation.
Possibly this should be the default behavior.
