java – Python下的间歇性“sslv3警报握手失败”

我有一个用JBoss编写的用 Java编写的REST API.最近我们将JVM从1.6更新到1.7.这开始只引起我们连接的 Python客户端的问题.间歇性地,Python客户端正在获得握手失败.我们写了一个非常简单的测试来重现问题：

import httplib2

for i in range(1,500):
    print i
    response,content = httplib2.Http(disable_ssl_certificate_validation=True).request('https://server.com:8443',)

提供以下输出：

Traceback (most recent call last):
  File "api_test/test.py",line 6,in <module>
    response,content = httplib2.Http(disable_ssl_certificate_validation=True).request('https://server.com:8443/rest/solidtumor/2012/id/50d3216c092c8554b8b9f384?glossary=true&api_key=APIKEY',)
  File "/home/hostovic/api_test/httplib2/__init__.py",line 1445,in request
    (response,content) = self._request(conn,authority,uri,request_uri,method,body,headers,redirections,cachekey)
  File "/home/hostovic/api_test/httplib2/__init__.py",line 1197,in _request
    (response,content) = self._conn_request(conn,headers)
  File "/home/hostovic/api_test/httplib2/__init__.py",line 1133,in _conn_request
    conn.connect()
  File "/home/hostovic/api_test/httplib2/__init__.py",line 914,in connect
    raise SSLHandshakeError(e)
httplib2.SSLHandshakeError: [Errno 1] _ssl.c:490: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure

第67次调用在此次运行中失败,但每次运行测试时都会在不同时间失败.

我们的其他客户端(Java,Groovy和Ruby)没有任何问题.

如果我将JVM切换回1.6,则故障停止.

我使用以下方法进行了openssl检查：

openssl s_client -connect server.com:8443

它返回了这个：

这似乎是正确的,但我不确定.如果它在每次通话中失败都会是一回事,但只是随机失败才真是奇怪.谁见过这个？
