This is a source parser bug.

gcj can fail to report an "exception must be caught or 
thrown" error depending on how the method that throws the
exception is invoked.
>How-To-Repeat:
The following code demonstrates the problem:

public class MustCatchOrThrow
{
  public static void main(String args[])
  {    
    new MustCatchOrThrow().test();    
  }
    
  private void test() throws Exception
  {
    throw new Exception();
  }
}

If the test method is invoked as follows, gcj correctly
reports an error:

MustCatchOrThrow m = new MustCatchOrThrow();
m.test();

>Release-Note:
Libgcj's java/net should be updated in order to compile
with the patches compiler. See
