#913 SignatureDeclareThrowsException is raised twice

[Nicolas Dordet]

In this case, the error SignatureDeclareThrowsException is raised twice instead of once :

public class BugSignature
{
public void record()
{
SwingWorker<string> worker = new SwingWorker<string>()
{
protected String construct() throws Exception
{
//
}
};
}
}</string></string>
