I installed lang-javascript and I see this in my log:

[2013-04-14 19:15:19,426][INFO][plugins] [Moondark]  
loaded [lang-javascript], sites []

When I post the following to the \_search api elasticsearch does not respond  
and the http request times out:

{  
"query":{  
"filtered":{  
"query":{  
"match\_all":{}  
},  
"filter":{  
"missing":{  
"field":"deletedAt",  
"existence":true,  
"null\_value":true  
}  
}  
}  
},  
"sort":[{  
"\_script":{  
"script":"doc['usernamesAssigned'].values.sort().join()",  
"type":"string",  
"lang":"js",  
"order":"asc"  
}  
}],  
"size":100  
}

This same query works fine on my development machine (mac os x). Is there a  
dependency Ubuntu doesn't have or something?

I figured it out. I needed log4j installed:

sudo apt-get install liblog4j1.2-java
