Class ThreadPermission

java.lang.Object

java.security.Permission

java.security.BasicPermission

org.elasticsearch.ThreadPermission

All Implemented Interfaces:

Serializable, Guard

public final class ThreadPermission
extends BasicPermission

Permission to modify threads or thread groups normally not accessible to the current thread.

SecureSM enforces ThreadGroup security: threads with RuntimePermission("modifyThread") or RuntimePermission("modifyThreadGroup") are only allowed to modify their current thread group or an ancestor of that group.

In some cases (e.g. test runners), code needs to manipulate arbitrary threads, so this Permission provides for that: the targets modifyArbitraryThread and modifyArbitraryThreadGroup allow a thread blanket access to any group.
