Tomcat unstable after updating apache http client
I ran into a strange issue the other day. Running tomcat 7.0.81. I have a
war file with apache http client vs 4.3.3. I was having some issues with my
code in the war and experimented with updating the http client to 4.5.3.
The result was bizarre.
Tomcat would start as normal but stop serving http requests after the first
request.
When running in the terminal, I couldn't stop tomcat with ctrl c. I had to
force close it with task mgr.
Is this expected?

Ill see if I can make a test war they'd reduces it to the minium.

No, not at all. Can you create a test war that demonstrates the issue?

Such DoS triggered by a simple client request is a security concern,
as the load is not proportional to the size of request.
It'd be better to send specific details to security@, not a public list
http://tomcat.apache.org/security.html
1. Take a thread dump (better: 3 of them in a sequence). What is
really going on should be visible there,
https://wiki.apache.org/tomcat/FAQ/Troubleshooting_and_Diagnostics#Common_Troubleshooting_Scenario
2. Tomcat 7.0.82 was released a few days ago.
