Description
URL.openConnection(Proxy.NO_PROXY) throws NULLPointerException.

The implementation of URL.openConnection(Proxy p) does not check whether the InetSocketAddress returned by p.address() could be null if user passes Proxy.NO_PROXY. This will result NULLPointerException when people tries to use the API.

SUGGESTED FIX public URLConnection openConnection(Proxy proxy) throws java.io.IOException { if (proxy == null) { throw new IllegalArgumentException("proxy can not be null"); } SecurityManager sm = System.getSecurityManager(); InetSocketAddress epoint = (InetSocketAddress) proxy.address(); ! if (epoint != null && sm != null) { if (epoint.isUnresolved()) sm.checkConnect(epoint.getHostName(), epoint.getPort()); else sm.checkConnect(epoint.getAddress().getHostAddress(), epoint.getPort()); } return handler.openConnection(this, proxy); }

EVALUATION Right, a security check is made on the address of the proxy without checking for the special case of NO_PROXY where the address is null. Very easy to fix. Will do as soon as possible. ###@###.### 2004-08-12

PUBLIC COMMENTS Add the null check to the method implementation will resolve the issue. A trivial fix, but important. ###@###.### 2004-08-12
