SOAP WS getPort（）中阻塞的线程-Performace问题+高CPU

Question

我已经使用WSDL创建了Java类，然后调用SOPA WS。在低负载下一切正常，但是随着负载的增加，线程开始进入BLOCKED状态。

CPU也很高。在分析线程转储时，似乎有些争用sun.net.www.protocol.jar.URLJarFile锁。

用于调用SOAP端点的代码

Service service = new Service();
UMarket uMarketSC = service.getUMarketSC(); // Getting pport
setEndpoint(uMarketSC, wsdlUrl);

public static void setEndpoint(Object port, String newAddress) {
    BindingProvider bp = (BindingProvider)port;
    Map<String, Object> context = bp.getRequestContext();
    context.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY,newAddress);

    context.put(SOAP_CONNECT_TIMEOUT, systemSettings.getExternalAdapterConnectionTimeout());
    context.put(SOAP_READ_TIMEOUT, systemSettings.getExternalAdapterReadTimeout());
}
