java.lang.reflect.UndeclaredThrowableException instead of java.net.ConnectException

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Write simple service interface with one method "String echo(String s)" 
without any throwable exceptions.
2. Use ProxyUtil.createProxy with JsonRpcHttpClient to create a proxy to this 
inerface.
3. Execute myService.echo("test"); with no server running which can handle 
JsonRpc Http request.

What is the expected output?
java.net.ConnectException expected. Also expected that I must declare try-catch 
as that is checked exception.

What do you see instead?
java.lang.reflect.UndeclaredThrowableException
Caused by: java.net.ConnectException: Connection refused

What version of the product are you using? On what operating system?
0.23

Please provide any additional information below.
I fixed that by adding java.net.ConnectException to throws declaration on each 
method of my service (String echo(String s) throws ConnectException). But is it 
really correct solution?

You're wrong in expecting "ConnectException" from a Proxy.  The basic rules of 
a Proxy is that it will only throw Exceptions defined by the interface that it 
is proxying.  All other exceptions are thrown as an 
UndeclaredThrowableException.
