Sets the maximum priority of the group. Threads in the thread
group that already have a higher priority are not affected.
<p>
First, the {@code checkAccess} method of this thread group is
called with no arguments; this may result in a security exception.
<p>
If the {@code pri} argument is less than
{@link Thread#PRIORITY_MIN} or greater than
{@link Thread#PRIORITY_MAX}, the maximum priority of the group
remains unchanged.
<p>
Otherwise, the priority of this ThreadGroupEx object is set to the
smaller of the specified {@code pri} and the maximum permitted
priority of the parent of this thread group. (If this thread group
is the system thread group, which has no parent, then its maximum
priority is simply set to {@code pri}.) Then this method is
called recursively, with {@code pri} as its argument, for
every thread group that belongs to this thread group.
@param pri the new priority of the thread group.
@throws SecurityException if the current thread cannot modify
this thread group.
