Summary: Uncaught Exception when Compiling Single File in Bad Package

Initial Comment:
I first noticed this bug when trying to compile an
Intermediate Language Level file, but I have been able
to repeat the same bug with a .java file.  The behavior
is not tied to language level / full java.

I am trying to compile a class with a bad package
statement--i.e., the file is in my home directory
(elspeth) but I have a statement at the top of the file
that says "package bob;"  Javac should catch this mistake.

However, when I "Compile Current Document", the
compiler output reports 1 error that is not a javac
error but instead an exception thrown from within
DrJava.   The text of the error is "The source file
/home/elspeth/MyClass.java is in the wrong directory or
the wrong package.  The directory name elspeth does not
match the package component bob."  I did a search of
the DrJava code base and found this error to be thrown
in some methods in DefaultGlobalModel.

If I instead "Compile All" I get the expected javac error.

This error is bad for two reasons.  The first is that
because it's an exception instead of a javac error, the
user isn't given line number feedback.  Perhaps more
seriously, this interferes with the fact that we don't
allow package statements at the Elementary and
Intermediate level--this execption shows up *instead*
of the correct Langauge Level error because it is
thrown before the language levels pass can start.

I have attached the file.
