Hello everyone,
(This is my first post to this list, so I am not 100% sure if this is
the right place).
I have run into a bug in the JDK HttpClient that was caused by a recent
commit:
http://hg.openjdk.java.net/jdk7u/jdk7u/jdk/diff/e6dc1d9bc70b/src/share/classes/sun/net/www/http/HttpClient.java
The method sun.net.www.http.HttpClient#available() can throw
java.net.SocketException, which can cause the creation of the HttpClient
to fail. This will happen if there is a connection in the cache that has
timed out and the socket has been closed.
I have attached a small patch that should resolve the problem, although
due to its intermittent nature I have not been able to verify with 100%
certainty.
The exception is:
Caused by: java.net.SocketException: Socket Closed

This issue also seems to affect JDK 6, and it appears that other people
have also run into this:

I attempted to file a bug for this on the Oracle website, however as far
as I can tell it was ignored.
