Guys,
I've just been refactoring some of the Jetty stuff, and it works fine
except for one thing. The second undeploy/deploy (of the plugin) cycle
barfs out trying to destroy Jetty with an IllegalAccessError.....

The Jetty code is simply trying to construct an instance of an inner
class, an event, to notify listeners of it's destruction :
if (_eventListeners!=null)
{
ComponentEvent event = new ComponentEvent(o); //
<-- HERE
for(int i=0;i<_eventListeners.size();i++)
{
EventListener listener =
(EventListener)_eventListeners.get(i);
if (listener instanceof ComponentEventListener)
((ComponentEventListener)listener).removeComponent(event);
}
}
I've had a look around for :
1. statics that might be causing a problem
2. any other deployed copies of jetty that might contain mismatched
versions of the class
could not find anything.
N.B. I am not changing any classes when this problem occurs - no APIs
have been altered.
I figure this must be a nasty side-effect of some exotic class-loading
that is going on. I am running on HEAD from last night, Sun 1.3.1,
Linux.
I shall try a couple of other JVMs and see if I can get more sense out
of them.
If anyone has any idea what could be causing this I would like to hear
from them, as Idon't want to check back my changes until I resolve this
problem.
Thanks for your time, Guys,
Jules
