Robert Muir commented on LUCENE-5471:
-------------------------------------
I think its a bug in your securitymanager config (e.g. you are missing
reflectpermission or something really necessary).
We use lucene in a securitymanager when running tests, see config here:

> Classloader issues when running Lucene under a java SecurityManager
> -------------------------------------------------------------------

> Key: LUCENE-5471
> URL: https://issues.apache.org/jira/browse/LUCENE-5471
> Project: Lucene - Core
> Issue Type: Bug
> Affects Versions: 4.5
> Reporter: Rick Hillegas
> Attachments: SecureLucene.java
>
>
> I see the following error when I run Lucene 4.5.0 under a java
> SecurityManager. I will attach a test program which shows this problem. The
> program works fine when a SecurityManager is not installed. But the program
> fails when I install a SecurityManager. Even more puzzling, the program works
> if I first run it without a SecurityManager, then install a SecurityManager,
> then re-run the program, all within the lifetime of a single JVM. I would
> appreciate advice about how to work around this problem:
