Description
FULL PRODUCT VERSION :


A DESCRIPTION OF THE PROBLEM :
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.

This method was added in a recent commit:

http://hg.openjdk.java.net/jdk7u/jdk7u/jdk/diff/e6dc1d9bc70b/src/share/classes/sun/net/www/http/HttpClient.java

The exception is:

The getSoTimeout() call should probably be in a try/catch block.
