Using 1.424 and 1.426 we have a similar issue. Both on windows and unix nodes it fails to download a jdk with connection refused exception.

On a unix node, when Jenkins tries to download http://download.oracle.com/otn-pub/java/jdk/6u26-b03//jdk-6u26-linux-i586.bin it gets a connection refused exception.

When using execute shell in a job on the same node with wget http://download.oracle.com/otn-pub/java/jdk/6u26-b03//jdk-6u26-linux-i586.bin it will start to download the jdk.

I have also tried to set the java_opts to pass in http.proxyPort and http.proxyHost but it still threw the same exception.

The changes to support oracle have changed from using the ProxyConfiguration class which used proxy settings to WebClient without setting the proxy or port details.

Still not working, on 1.432. Our proxy settings aren't using username/password. This is what I get:
