-------------------------------------------
Just to note, that I also saw this in recent test runs against older branches
(10.6 and 10.3) with ibm 1.6.
> Access denied ("java.lang.RuntimePermission" "modifyThread") in
> store.RecoveryAfterBackup test

> 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?
