Very nice presentation.
Can I have access at the samples and/or slides? Are they available somewhere on the net?
Thanks.

But there are some very small mistakes in the sample code I downloaded from git.springsource.org/s2gx-2010/concurrent-progr... :
- * In the pom.xml file from the project "messaging", the activemq-core dependency should exclude its spring-context transitive dependency. Failing to do so brings version 2.5.6 of spring-context and its transitive dependencies to the project, which results in some compilation errors (like the error "The type ApplicationListener is not generic; it cannot be parameterized with arguments <ApplicationEvent>" present in SimpleEventListener.java). The following config should do the trick (notice the exclusion):
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-core</artifactId>
<version>${org.apache.activemq.version}</version>
<exclusions>
<exclusion>
<groupId>org.springframework</groupId>
<artifactId>spring-context</artifactId>
</exclusion>
</exclusions>
</dependency>
- * In the CounterDemo.java from the project "concurrency", there is a comment that reads "also try: newSingleThreadPool, newFixedThreadPool(2)". That newSingleThreadPool should be newSingleThreadExecutor() .
- * Still in CounterDemo.java and not really a bug: the line int loop = 100000; (hundred thousand) should really be int loop = 1000000; (a million). That way, it would be exactly like the presentation and better demonstrate the "Performance Myth-buster" which you explained in the presentation and in that README.TXT. =)
Thanks again for the presentation, slides and code.
