当同时且足够快地运行Resteasy客户端（版本3.0.6.Final）时，我总是得到：

此类问题从未出现在常规调用（低并发）中，因此SSL初始化应该没问题：
// load the certificate
InputStream fis = this.getClass().getResourceAsStream("/path/to/redlink-CA.crt");
CertificateFactory cf = CertificateFactory.getInstance("X.509");
Certificate cert = cf.generateCertificate(fis);
// load the keystore that includes self-signed cert as a "trusted" entry
KeyStore keyStore = KeyStore.getInstance(KeyStore.getDefaultType());
keyStore.load(null, null);
TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
keyStore.setCertificateEntry("CA", cert);
tmf.init(keyStore);
SSLContext ctx = SSLContext.getInstance("TLS");
ctx.init(null, tmf.getTrustManagers(), null);
// build the rest client
ResteasyClientBuilder clientBuilder = new ResteasyClientBuilder();
clientBuilder.sslContext(ctx);
所以我没有想法如何找到这个问题的来源，这很难调试。
