-------------------------------------------------------------------------------------
Key: XMLRPC-144
URL: https://issues.apache.org/jira/browse/XMLRPC-144
Project: XML-RPC
Issue Type: Bug
Components: Source
Affects Versions: 3.1
Environment: n/a
Reporter: Steve Cohen
Fix For: 3.1
When an HTTP 307 Redirect packet is returned to a Client using the latest
source code, the following exception is thrown:
java.nio.charset.IllegalCharsetNameException:

It is not hard to see why this happens, looking at the source code which begins
on line 173 of org.apache.xmlrpc.client.XmlRpcCommonsTransport:
173 try {
174 currentUri = method.getURI();
175 String charset = currentUri.getURI();
176 redirectUri = new URI(location, true, charset);
177 method.setURI(redirectUri);
178 } catch (URIException ex) {
On line 175, the currentUri.getURI() method is called, storing a string
representation of the URI in the
variable charset. On line 176, the charset variable is fed into a new URI
constructor, as a parameter that is supposed to represent the "the charset
string to do escape encoding, if required". Since this is a URI, and not the
name of a valid charset, the exception is thrown.
I suppose this code must only have been tested when escape encoding was not
required, so this wasn't seen before. I will be including a patch to fix this.
