WS connection lock

Question

Hello!
I have next configuration:
ws client <- -> service (soap/http) <- -> osb business service <- one-way ssl -> ws provider (basic authentification)
jms client <- -> service (soap/jms) <- -^
Problem:
If run load test ws client - service work fine, but if in moment this test jms client send message then ws service and jms service have locks by 2 min.
ThreadStackDump contains:
"[ACTIVE] ExecuteThread: '39' for queue: 'weblogic.kernel.Default (self-tuning)'" waiting for lock java.util.Vector@6a692986 BLOCKED
                 java.util.Vector.isEmpty(Vector.java:279)
                 weblogic.net.http.KeepAliveCache.get(KeepAliveCache.java:150)
                 weblogic.net.http.HttpClient.findInCache(HttpClient.java:230)
                 weblogic.net.http.HttpsClient.New(HttpsClient.java:499)
                 weblogic.net.http.HttpsURLConnection.connect(HttpsURLConnection.java:239)If don't use ssl then problem go away.
Do you have ideas about problem?
Thanks

Hi,
Maybe this is caused by the Vector is synchronized instead of the List, if so there is this limitation in the WLS http connection. Not sure whether you can use the JDK https connection instead:
System.setProperty("java.protocol.handler.pkgs", "com.sun.net.ssl.internal.www.protocol");
HTH,
