Hi,

I'm writing analyzer plugin for es 5.2.1 on ubutnu 14.04.

After restart, when cluster is green and the plugin is loaded,

I run simple analyze command for testing and I get this error..

curl -XGET 'localhost:9200/\_analyze?pretty' -d '  
{  
"analyzer" : "my\_spanish\_analyzer",  
"text" : "this is a test"  
}'

there is no response and the cluster performing restart...

(getClassLoader is a part from my analyzer code )

Any ideas ?

Thanks.

YAY !!!  
Thanks David !!!

Fixed with _plugin-security.policy_ file at plugin-metadata dir :

grant {  
permission java.io.FilePermission "MY\_PATH", "read";  
};

And:

```
     SecurityManager sm = System.getSecurityManager();
    if (sm != null) {
        // unprivileged code such as scripts do not have SpecialPermission
        sm.checkPermission(new SpecialPermission());
    }

    AccessController.doPrivileged( SOME_CODE... );
```
