Date Sun, 07 Feb 2016 12:44:39 GMT
Johann created HTTPCORE-419:
-------------------------------

             Summary: Catch NullPointerExceptions (NPE) in BHttpConnectionBase#close()
                 Key: HTTPCORE-419
                 URL: https://issues.apache.org/jira/browse/HTTPCORE-419
             Project: HttpComponents HttpCore
          Issue Type: Improvement
          Components: HttpCore
    Affects Versions: 4.4.4
         Environment: Google App Engine
            Reporter: Johann


Google App Engine occasionally throws a NullPointerException when calling {{Socket#shutdownInput()}}
and {{Socket#shutdownOutput}}. Here are some stack traces:

{code}
Uncaught exception from servlet
java.lang.NullPointerException
     at com.google.appengine.api.socket.SocketApiHelper.translateError(SocketApiHelper.java:100)
     at com.google.appengine.api.socket.SocketApiHelper.translateError(SocketApiHelper.java:119)
     at com.google.appengine.api.socket.SocketApiHelper.makeSyncCall(SocketApiHelper.java:85)
     at com.google.appengine.api.socket.AppEngineSocketImpl.shutdownOutput(AppEngineSocketImpl.java:678)
     at java.net.Socket.shutdownOutput(Socket.java:1544)
     at org.apache.http.impl.BHttpConnectionBase.close(BHttpConnectionBase.java:325)

Uncaught exception from servlet
java.lang.NullPointerException
     at com.google.appengine.api.socket.SocketApiHelper.translateError(SocketApiHelper.java:100)
     at com.google.appengine.api.socket.SocketApiHelper.translateError(SocketApiHelper.java:119)
     at com.google.appengine.api.socket.SocketApiHelper.makeSyncCall(SocketApiHelper.java:85)
     at com.google.appengine.api.socket.AppEngineSocketImpl.shutdownInput(AppEngineSocketImpl.java:664)
     at java.net.Socket.shutdownInput(Socket.java:1514)
     at org.apache.http.impl.BHttpConnectionBase.close(BHttpConnectionBase.java:329)
{code}

Would it be possible to catch those NPEs so I don't have to override the class manually?
