Hi

I try to develop an x-pack extension which, as it seems, requires SecurityPermission to insertProvider.BC.  
So i put this in my _x-pack-extension-security.policy_:

```
grant {
  permission java.security.SecurityPermission "insertProvider.BC";
};

```

This is being picked up by the x-pack/extension install script, showing that it needs to grant these permissions.

However, when I start elasticsearch i'm still getting the following:

```
java.security.AccessControlException: access denied ("java.security.SecurityPermission" "insertProvider.BC")

```

Am I doing something wrong or has this been disabled for security reasons?

You need to wrap your code requiring the permission inside a doPrivileged block. Have you read the [plugin author help page](https://www.elastic.co/guide/en/elasticsearch/plugins/current/plugin-authors.html#plugin-authors-jsm)?

Thought I did that, or the check for permission did already fail.  
Nevermind it's working now.
