I got a report of the following intermittent (6/60) exception in
store.RecoveryAfterBackupTest.
Exception in thread "main" java.security.AccessControlException: Access denied

modifyThread is a necessary permission if interrupting a thread other than the
current thread but is not in our policy file for derby.jar.
The relevant code in ContextService is:
for (ContextManager cm : allContexts) {
Thread active = cm.activeThread;
if (active == me)
continue;
if (active == null)
continue;
final Thread fActive = active;
if (cm.setInterrupted(c))
{
AccessController.doPrivileged(
new PrivilegedAction<Void>() {
public Void run() {
fActive.interrupt();
return null;
}
});
}
I am not sure why this has never come up before. Are we expecting in this
context that fActive is the current thread?
