In this page of the Tomcat 7 documentation - but this is true for all versions - there is the following statement:

"The resource factory will create a new instance of the appropriate bean class every time a lookup() for this entry is made."

But that seems not true. I created an example foo.bar.Bean, which simply increment a static int at each creation. Then, I configured a BeanFactory in the global resources section of server.xml, and I deployed a servlet which simply lookup 1000 thousand times for the bean and print its string representation in the response. 

To reproduce, follow the steps below using the targz attached:

1) configure a resource with a BeanFactory, as in the server.xml attached;
2) put the bean-factory-bug-bean.jar in the common classpath of the container;
3) start the container;
4) deploy the bean-factory-bug-web.war file in the appbase folder;
5) open http://localhost:8080/bean-factory-bug-web/BeanServlet

As for one can read from the documentation, the expected output is 

Bean #1
Bean #2
Bean #3
...
Bean #999
Bean #1000

But the actual output is

Bean #1
Bean #1
Bean #1
...
Bean #1
Bean #1

I think that the actual behaviour of the container is the most advisable behaviour, but would be better to update the documentation to match it and avoid misleading.

Thanks.
