> Key: DERBY-5571
> URL: https://issues.apache.org/jira/browse/DERBY-5571
> Project: Derby
> Issue Type: Bug
> Components: Services
> Affects Versions: 10.8.2.2
> Reporter: Kathey Marsden
> Labels: derby_triage10_10
>
> IndexStatisticsDaemonImple.schedule() has the following code. setDaemon can throw a SecurityException so should be wrapped. It says: SecurityException - if the current thread cannot modify this thread.
> Does this mean that our documentation should require modifyThreadGroup privs too?
> Currently it is in our test policy but not the documentation:
> // These permissions are needed by AssertFailure to dump the thread stack
> // traces upon failure.
> //permission java.lang.RuntimePermission "getStackTrace";
> permission java.lang.RuntimePermission "modifyThreadGroup";
> // If we're idle, fire off the worker thread.
> if (runningThread == null) {
> runningThread = new Thread(this, "index-stat-thread");
> // Make the thread a daemon thread, we don't want it to stop
> // the JVM from exiting. This is a precaution.
> runningThread.setDaemon(true);
> Marking as a regression as a security violation could make existing statements fail.
