RE: [jbosscache-dev] HEAD
by Vladimir Blagojevic
I will also merge my partial state transfer changes to HEAD related to
RegionManager,Region,TreeCache.
If I had a vote I would vote to put JBC alpha/DR2 to AS5 beta instead of
this JBC beta.

HEAD
by Manik Surtani
Brian,
I've started work on merging the Region/RegionManagers for eviction.
The interfaces and API are now in place, but it breaks in a few
places, stuff that's still WIP.
Hopefully at least you can go ahead with your integration, I will
have it all functional by tomorrow though. And then the rest of
tomorrow and thu to stabilise as much as I can before I release on Fri.
Do you think we can get away with a .DR2 or Alpha instead of a Beta?
Because this certainly isn't Beta quality. :-)

Re: optimistic opt idea
by Manik Surtani
Hmm, interesting idea, especially that 2.0.0 is baselined on Java5.
How would such objects be loaded into the cache in the first place?
Perhaps just the initial modification (creation of the object in
cache) and thereafter treated as immutable?

RE: [jbosscache-dev] Build failure with J2SE 1.4.2_13
by Brian Stansberry
It produces a 1.4 compatible binary (jboss-cache.jar), but JDK 5 is
needed to build. It also produces a binary jboss-cache-jdk50.jar that
requires JDK 5 at runtime. The two jars are identical except the latter
has a few annotation classes included.

Expose getLocalAddress and getMembers in Cache
by Brian Stansberry
Methods getLocalAddress and getMembers were in the public API of
TreeCache but now you need to cast to CacheSPI to get access to them.
Can we move them back to Cache? I've seen references to both on forums
and support cases, so I think they are used. Clustered SSO uses
getLocalAddress() -- I worked around it by using CacheSPI, but would
prefer not doing that.

(Don't know if this has impact on other parts of the code, so FYI here.)
I have pinpointed (at least part of) the problem to
TreeCache.loadState() where now instead of sending the exception in rsp
(response), we now throw it directly from TreeCache. Therefore, we
didn't catch the TimeoutException and re-try the state transfer part.
I have created a Jira for this

Manik asked me a similar question a couple days ago about some BR state
transfer tests that were failing. I didn't know. But it looks like
those tests are passing now; perhaps whatever he figured out will work
for the aop ones as well.
I was trying to look at the post- 11/01/06 jbosscache-testsuite-140 cc
