Cocoon 2.1.3 - IllegalStateException:disposed ComponentLocator with webdav mounts

[Christian Mayrhuber <ch...@gmx.net>]

Hi,

If I access the /samples/ page with only one client, everything goes 
right, if I access it with two or more concurrent clients I get lots
of IllegalStateExceptions.
Everything goes well with parallel execution if I do not mount the 
samples remote, but use the FileSource. Is there some concurrency 
problem in ECM?

To reproduce:
Copy the cocoon-2.1.3 samples onto a webdav server and mount this 
directory with the webdav protocol in the webapp sitemap.
<map:match pattern="samples/**">
    <map:mount check-reload="yes" 
src="webdav://fiicmpc141.tu-graz.ac.at:8080/samples/{1}" 
uri-prefix="samples/{1}"/>
</map:match>

Apache Bench was used to test concurrency:
ab -n20 -c1 http://cocoonhost:8888/samples/ succeeds with no errors
ab -n20 -c2 http://cocoonhost:8888/samples/ fails with 
IllegalStateExceptions

System is SMP RedHat 7.3 with latest RHSA 2.4.20 kernel.

Java VM is
java version "1.4.2_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_02-b03)
Java HotSpot(TM) Server VM (build 1.4.2_02-b03, mixed mode)
with LD_ASSUME_KERNEL=2.2.5

The Servlet Container is Jetty/4.2.9, cocoon default.
