Re: [jboss-dev] org.jboss.util.threadpool.BasicThreadPool issue
I'm not making use of anything, Scott wrote this code. :-)
The issue looks to be related to the conversion
of the code from using Heap (which returns null when empty)
to PriorityQueue.
http://viewvc.jboss.org/cgi-bin/viewvc.cgi/common/common-core/trunk/src/m...
Contrary to your comment, PriorityQueue throws an Exception
when empty on the remove() as opposed to remove(Object):
http://java.sun.com/j2se/1.5.0/docs/api/java/util/AbstractQueue.html#remo...
A simple check for isEmpty() and return null
(assuming the code is already thread safe) should stop the logging?

with some progressive changes in my AS5 trunk workspace, while

I am still checking why this issue is happening. But I see that you are
making use of a PriorityQueue and whose remove is supposed to be safe
from any exception.
