logstash 1.1.0 Betas do not work in Windows

With logstash.conf as follows :

input {
file {
type => "log4j"

path => [ "C:/NewCommServer/logs/commserver.log", "C:/NewCommServer/logs/commserver.log.*" ]
}

}

output {

1. Emit events to stdout for easy debugging of what is going through

2. logstash.
   stdout { }

1. You can have multiple outputs. All events generally to all outputs.

2. Output events to elasticsearch
   elasticsearch {

3. Setting 'embedded' will run a real elasticsearch server inside logstash.

4. This option below saves you from having to run a separate process just

5. for ElasticSearch, so you can get started quicker!
   embedded => true
   }
   }

Running the command line :

C:\NewCommServer\logger>java -jar logstash-1.1.0beta7-monolithic.jar agent -f logstash.conf – web --backend elasticsearch://127.0.0.1/?local

On Windows 2008 R2 SP2, and :

C:\NewCommServer\logger>java -version
java version "1.7.0"
Java(TM) SE Runtime Environment (build 1.7.0-b147)
Java HotSpot(TM) 64-Bit Server VM (build 21.0-b17, mixed mode)

C:\NewCommServer\logger>java -jar logstash-1.1.0beta7-monolithic.jar agent -f logstash.conf – web --backend elasticsearch://127.0.0.1/?local

and logging files available and present on disk with data being written into them I get the following ruby issue ...

C:\NewCommServer\logger>java -jar logstash-1.1.0beta7-monolithic.jar agent -f lo

The server continues to run but does not retrieve anything from the tailed files to populate queries I make to elasticsearch.
