Well, I created a context file named for my app (Spc.xml) and placed it
in ${CATALINA_HOME}/conf/Catalina/localhost/. I set the two entries:
<antiJARLocking>true</antiJARLocking>
<antiResourceLocking>true</antiResourceLocking>
The Tomcat logs show:
2009-10-09 16:03:11,093 DEBUG main
org.apache.catalina.startup.ContextConfig - Successfully processed
context [/Spc] configuration file
D:\apache-tomcat-6.0.18\conf\Catalina\localhost\Spc.xml null
[Almost a four minute delay]
2009-10-09 16:07:04,984 DEBUG main
org.apache.catalina.core.StandardContext - Starting /Spc
and the thread dumps still show a similar state, with the:
at java.io.FileOutputStream.close0(Native Method)
at the top of the "main" thread.

/dev/random is the system-provided random byte stream for UNIX/Linux and
some other platforms. In order to generate a reasonably random
sequence, it needs sources of randomness, such as keyboard interrupts,
mouse movements, radioactive decay; than randomness is termed entropy,
and until there's enough of it, the stream will block when requests are
made to it.

The above is the interesting one: it's stuck in close(), waiting for
something in the underlying file system. Since you're on Windows, you
may need to set the antiJARLocking and antiResourceLocking attributes in
the <Context> element for your webapp.
