Hi there,

When I perform a rename refactor action, a '_new' string is automatically appended to the search item, so I can't rename anything anymore.

When the cursor locate at the `getFoo`, and press Ctrl+Shift+R, which performs a rename action. In the Search and Replace dialog, the search item become `getFoo_new`, and the default replace item also `getFoo_new`, so there is no match content can be rename. 

// Some comments here
int getFoo()
{
    return foo;
}
