Well - it looks like this modifyThreadGroup permission is checked when
getting ThreadGroup.getParent only when it reaches the "rootGroup", which
is supposedly somehow special (
http://grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/6-b14/java/lang/SecurityManager.java#SecurityManager.getRootGroup%28%29).
Is there a reason to actually need to show this rootGroup ? In general,
this should only happen when new Threads are created, which is why this is
restricted in GAE:
* Throws a <code>SecurityException</code> if the
* calling thread is not allowed to modify the thread group argument.
* <p>
* This method is invoked for the current security manager when a
* new child thread or child thread group is created, and by the
* <code>setDaemon</code>, <code>setMaxPriority</code>,
* <code>stop</code>, <code>suspend</code>, <code>resume</code>, and
* <code>destroy</code> methods of class <code>ThreadGroup</code>.
* <p>
* If the thread group argument is the system thread group (
* has a <code>null</code> parent) then
* this method calls <code>checkPermission</code> with the
* <code>RuntimePermission("modifyThreadGroup")</code> permission.
* If the thread group argument is <i>not</i> the system thread group,
* this method just returns silently.
* <p>
* Applications that want a stricter policy should override this
* method. If this method is overridden, the method that overrides
* it should additionally check to see if the calling thread has the
* <code>RuntimePermission("modifyThreadGroup")</code> permission, and
* if so, return silently. This is to ensure that code granted
* that permission (such as the JDK itself) is allowed to
* manipulate any thread.
In general, this is not necessarily a restriction of GAE, this is plain
"java" security check, not something that GAE has added. Granted, this
wouldn't be an issue when running under a servlet container w/o a
SecurityManager.
In any case, I'm just bringing it up for this issue to be known. I know
that in the past , the Tapestry devs have made adjustments to allow for the
widest out-of-the-box compatibility of the framework (e.g. so that it can
work w/ Scala, deploy on AppEngine, etc). As you indicated, there are
workarounds for this, yet for anyone attempting to upgrade from 5.3.7 to
5.4 this would represent a regression in functionality (and really, is it
THAT important to be able to show the list of threads (see attached
screenshot) - at least at first glance, doesn't seem neither too important
or helpful.
