Hangs on startup
Hey,
When i use the following code felix will hang on startup. When i type in the
command "ps" it appears to resume the startup. It appears that the
UUID.randomUUID() or the InetAddress.getLocalHost() lines will cause it to
hang. If i comment both out, then it starts just fine.
package org.dav.proxy;
import org.osgi.framework.*;
public class ProxyServerActivator implements BundleActivator {
ProxyServer proxyServer;
public void start(BundleContext ctxt) throws Exception {
System.out.println("activator starting...a");
proxyServer = new ProxyServer("F:\\apps\\Isis\\ProxyServer\\"); // this
will hang, read next class to see where it is hanging.
System.out.println("activator starting...b");
}
public void stop(BundleContext ctxt) throws Exception {
}
}
package org.dav.proxy;
import java.io.*;
import java.net.*;
import java.util.*;
public class ProxyServer {
UUID id = UUID.randomUUID(); // this will cause it to hang, if i comment
this out, it does not hang.
protected ProxyServer(String homePath) throws IOException {
System.out.println("ProxyServer()a");
InetAddress.getLocalHost(); // this line causes it to hang, if i comment
this out, it does not hang.
System.out.println("ProxyServer()b");
InetAddress.getLocalHost().getHostAddress();
System.out.println("ProxyServer()c");
}
}
here is my manifest.mf file

Main-Class: org.dav.proxy.ProxyServer
Bundle-Version: 1.0.0
Bundle-Activator: org.dav.proxy.ProxyServerActivator

Re: Hangs on startup
Posted by Patrick Forhan <fe...@muddyhorse.com>.
We've had cases where eclipse just wasn't able to run felix reliably.
You could usually get it to work by hitting enter one or more times
every so often.
That was with the felix text shell bundle installed. When we took out
that bundle (org.apache.felix.shell.tui) things seemed to be pretty
normal. I think there were defects filed with both felix and eclipse,
but I don't think any definite activity happened from either end.

I cannot remember what the issue is, but we have seen other cases where
people have run into difficulty when running from inside of Eclipse.
Anyone remember what the issue was?

Hey,
Yes, i am running it inside eclipse. I setup a run configuration. I tried
running it on the command line outside of eclipse and it seems to startup
just fine. Why cant i run it inside of eclipse? Is there some special
setting i need to do? Otherwise i guess i can just run it on the command
line.
thanks.

I can't reproduce this on my mac. Are you doing anything special like
running inside eclipse or something?
Furthermore, can you give me thread dump of a hang? You can create it
in windows either using the jmx console or by hitting ctrl-break
