-Policy-based Java sandbox with instrumentation support for online judges.
+Java class sandbox with instrumentation support for online judges. 
 
 It implements:
 
-* [**security policy-based sandboxing**](https://docs.oracle.com/javase/7/docs/technotes/guides/security/PolicyFiles.html) (see [**DMOJ/judge**](https://github.com/DMOJ/judge) for [example policy](https://github.com/DMOJ/judge/blob/master/dmoj/executors/java-security.policy))
 * a much faster, [unsynchronized ASCII-only `System.out` stream](https://github.com/DMOJ/java-sandbox-agent/blob/master/src/main/java/ca/dmoj/java/UnsafePrintStream.java) that's suitable for single-threaded online-judging scenarios
 * support for **disallowing particular classes from being loaded**, to force certain solutions trivialized by the standard library
 * optional **unbuffering of standard output**, for interactive problems without requiring users to flush manually
