James E. King, III commented on THRIFT-2935:
--------------------------------------------

Wouldn't user-created exceptions derive from TApplicationException?

>             Project: Thrift
>          Issue Type: Wish
>          Components: Java - Compiler
>    Affects Versions: 0.9.2
>            Reporter: Sergei Egorov

> Exceptions in Java should not extend TException to avoid collisions on method signature for better IDE support. Currently, if service is throwing some thrift exception, i.e. TMyCustomException, it will have following signature:
> public void myMethod() throws TMyCustomException, TException {
> }
> But TMyCustomException is overlapped by TException,
> Now, if we will call this method in our code:
> client.myMethod();
> IDE will propose to generate try\catch with only 1 block: 
> try {
>    client.myMethod();
> } catch(TException e) {
> }
> Because TMyCustomException extends TException. If TMyCustomException will extends just Exception, than IDE will generate following code:
> try {
>    client.myMethod();
> } catch(TMyCustomException e) {
> } catch(TException e) {
> }
> which is much better, because client caller will know about any custom(!) thrift exception in this method.
> Thanks!
