------------------------------------------
Summary: Sometimes get a broken pipe error in Java 11 when trying
to connect with HttpClient
Key: HTTPCLIENT-2032
URL: https://issues.apache.org/jira/browse/HTTPCLIENT-2032
Project: HttpComponents HttpClient
Issue Type: Bug
Components: HttpClient (classic)
Affects Versions: 4.5.10

Connecting with httpclient expecting to get a handshake and/or certificate
error but sometimes get a broken pipe error (and sometimes I get the desired
handshake / certificate error).
It works perfectly fine in Java 8.

As you can see, the SessionOutputBufferImpl tries to flush but hits the broken
pipe. Could it be that the socket has already flushed itself sometimes and thus
resulting in the connection/socket being closed before the explicit flush is
called?
