jetty.io.EofException java.io.IOException: Broken pipe

在apache + mod_proxy + jetty下，单台服务器，50并发情况下，jetty异常

mod_proxy配置如下：

<IfModule mod_proxy.c>
    ProxyRequests Off
    ProxyPreserveHost On
    <Directory proxy:*>
        Order deny,allow
        Allow from all
    </Directory>

    ProxyPassMatch ^/(stream|user|friend|suggest|notice|upload|privatemsg|comment|common|search|score|ta|tfa)/(.*)$ http://localhost:8080 min=5 smax=16 ttl=6
00 timeout=100
</IfModule>

 找到两种解决方法，但都无法根治问题，实际上只是使得jetty不再抛出异常

1、在环境变量中设置： _JAVA_SR_SIGNUM = 12

参考：https://www.evernote.com/shard/s95/sh/33fe6db4-03a2-45d5-b7a3-6a6c35e5d864/a88a0f85148d56fe96e3b0df83ff7349

 

2、将jetty io类UncheckedPrintWriter crack掉

其中的属性_throwUnchecked=true正式控制异常是否向上抛出的开关，把它修改掉，然后将这个class单独打成jar包。
