Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:


Java has its own rules for what constitutes a line terminator.

A bare \r is one, as is a bare \n; but the \r\n sequence is also
considered a single terminator.

I've run across Java source code which uses a mix of different line
terminators in a single file.  While ugly, there's not much I can do
about it.

If I compile code like this with gcj, and then use gdb to debug it, I
find that the debug arrow will be misplaced, because Emacs and gcj
disagree about the current line number.  Similarly, M-x next-error
will sometimes jump to the wrong line, as gcj reports line numbers
according to Java rules, but Emacs interprets them according to its
own rules.

I think in java-mode Emacs ought to respect Java's notion of line
termination.
