Enrico Olivelli commented on KAFKA-1101:
----------------------------------------
Awesome solution! it works, here is my code:
{code}
public class NoExitSecurityManager extends SecurityManager {
private final SecurityManager wrapped;
public NoExitSecurityManager() {
wrapped = null;
}
public NoExitSecurityManager(SecurityManager wrapped) {
this.wrapped = wrapped;
}
@Override
public void checkExit(int status) {
super.checkExit(status);
throw new SecurityException("System.exit is disabled on unit tests");
}
@Override
public void checkPermission(Permission perm) {
if (wrapped == null) {
return;
}
wrapped.checkPermission(perm);
}
}
{code}
Using JUnit it is simple to add this fake SecurityManager
{code}
@BeforeClass
public static void disableSystemExit() {
System.setSecurityManager(new NoExitSecurityManager());
}
{code}
I found a similar security manager in Groovy code

> URL: https://issues.apache.org/jira/browse/KAFKA-1101
> Project: Kafka
> Issue Type: Bug
> Reporter: Jason Rosenberg
>
> We embed the KafkaServer inside a java service container framework, which
> makes it easy to deploy and monitor within our infrastructure. When
> upgrading to kafka 0.8 from 0.7.2, I ran into an issue with not being able to
> pass the needed constructor arg (SystemTime), since there doesn't appear to
> be an easy way to instantiate that from java. So, I ended up with this janky
> solution using SystemTime$.MODULE$.
> Could a default constructor be added which assumes a default SystemTime,
> rather than requiring that here?
> Note, I need to construct a KafkaServer directly, since I need to manage the
> lifecycle more directly than can be done with KafkaServerStartable.
> {code}
> // Need to do janky scala MODULE$ dereferencing, in order to get a
> default value in ctor
> server = new kafka.server.KafkaServer(kafkaConfig, SystemTime$.MODULE$);
> server.startup();
> {code}
