[Bug java/16439] New: gcj doesn't generate proper debugging line number info

["jjohnstn at redhat dot com" <gcc-bugzilla@gcc.gnu.org>]

For the following test case in the gdb testsuite: jmain.java

public class jmain
{
  public static void main (String[] args)
    {
        return;
    }
}

The breakpoint for main ends up being line 4 (the open brace) instead of line 5.
 This does not match the C/C++ behavior which is to point to the first statement
of the member function.  Gdb gets the line number info from the compiler which
is the following tailed output from readelf -wl

 Line Number Statements:
  Extended opcode 2: set Address to 0x8048868
  Special opcode 8: advance Address by 0 to 0x8048868 and Line by 3 to 4
  Special opcode 89: advance Address by 6 to 0x804886e and Line by 0 to 4
  Special opcode 175: advance Address by 12 to 0x804887a and Line by 2 to 6
  Special opcode 28: advance Address by 2 to 0x804887c and Line by -5 to 1
  Special opcode 89: advance Address by 6 to 0x8048882 and Line by 0 to 1
  Advance PC by 14 to 8048890
  Extended opcode 1: End of Sequence
