[Design of JBossCache] - Re: Locking tree before setting initial state
by bstansberry＠jboss.com
Thought a bit about the idea of locking / on the state recipient before it calls channel.getState(). The idea is to ensure that the received state can be integrated w/o concern about not being able to acquire the required read lock. Problems I see:
1) Race with the state provider, where the provider issues a prepare while the recipient issues getState(). Result is a deadlock until either the state transfer or the prepare() times out, or the tx that issued the prepare is rolled back on the state provider.
Actually, even worse. The prepare() call will be waiting to lock / and blocking the jg uphandler thread on the state recipient . That will prevent receipt of any rollback() message or any subsequently transferred state, so the state transfer will be unable to go through until the prepare() fails with a lock timeout.
2) Race with a 3rd node in the cluster where the prepare() gets to the state provider before the getState() call. Again deadlock until the prepare() times out.

[Design of JBoss Serialization] - InstantiationException: java.util.HashMap$Values
by bos
I'm returning a rather deep and complex object structure from an ejb3 stateless session bean to another, deployed in two different ears. The initiating bean is annotated with JSR-181 WS annotations. I'm running on 4.0.4.GA with jdk1.5.0_08 and have tried with both serialization 1.0.1 and 1.0.2. On returning from the session bean I get the following exception. Any ideas to what the cause may be or what I can do to further investigate?

[Design of JBoss internal QA (Test Suite)] - Failures/Errors in running test suites in jboss-4.0.4.GA-src

I executed test suites in jboss-4.0.4.GA-src using "./build.sh tests". Overall, I got the following failures. Does anyone known what is going on? I do run the suites for many times, but got different failures. Is it undeterministic? My machine is Linux with jvm 1.4.2_10.
