Hi, I have spent almost a couple of days trying to resolve this issue to no
avail, so any help would be much appreciated.
I am intercepting GWT calls using Spring MVC through a custom
GwtRpcController class. The method of interest is as follows:
@Override
public String processCall(String payload) throws SerializationException
{
try {
RPCRequest rpcRequest = RPC.decodeRequest(payload,
this.remoteServiceClass);
// delegate work to the spring injected service
return RPC.invokeAndEncodeResponse(this.remoteService,
rpcRequest.getMethod(), rpcRequest.getParameters() );
} catch (IncompatibleRemoteServiceException ex) {
getServletContext().log("An IncompatibleRemoteServiceException
was thrown while processing this call.", ex);
return RPC.encodeResponseForFailure(null, ex);
} catch (UnexpectedException ex) {
if (ex.getCause() instanceof
org.springframework.security.access.AccessDeniedException) {
AccessDeniedException clientEx = new
AccessDeniedException();
getServletContext().log("A Spring AccessDeniedException was
thrown while processing this call.", clientEx);
return RPC.encodeResponseForFailure(null, clientEx);
} else {
throw ex;
}
}
}
As you can see, I am catching the Spring Access Denied Exception which
comes from the @PreAuthorize annotation in my methods, and using
RPC.encodeResponseForFailure to pass my custom Exception (extends
RuntimeException(as does GWT's own InvocationException), implements
IsSerializable, and has a zero argument constructor). Here's the code if
you want to refer:
package com.fundwave.fundadmin.shared;
import com.google.gwt.user.client.rpc.IsSerializable;
public class AccessDeniedException extends java.lang.RuntimeException
implements IsSerializable {
private static String AUTHORIZATION_ERROR = "Authorization Error: ";
private String message;
public AccessDeniedException() {
super(AUTHORIZATION_ERROR+"Your account does not have the rights to
perform this action.");
this.message = AUTHORIZATION_ERROR+"Your account does not have the
rights to perform this action.";
}
public AccessDeniedException(String msg) {
super(AUTHORIZATION_ERROR+msg);
this.message = AUTHORIZATION_ERROR+msg;
}
public AccessDeniedException(Throwable t) {
super(t);
}
public AccessDeniedException(String msg, Throwable t) {
super(AUTHORIZATION_ERROR+msg, t);
this.message = AUTHORIZATION_ERROR+msg;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
On the client side, my code painlessly catches my custom exception in the
development mode:
caught.printStackTrace();
if (caught instanceof AccessDeniedException) {
serverResponseLabel.setText("Error: " + caught.getMessage());
}
Surprisingly, after compiling, I get the following error:
Error: (TypeError) stack:

lineNumber: 36006 columnNumber: 2: this$static[signature][0] is not a

If it runs great in dev mode, what could cause the issue after compilation?
I have tried with the latest GWT release (2.6) as well as the penultimate
release.
