I was testing a fix for IZ 83830 (IAE when using a Function Breakpoint)
and noticed another problem. If my project is located in directory with 
spaces, there is NPE in EditorContextBridge.annotate():

java.lang.NullPointerException

    public static Object annotate(CallStackFrame csf, String annotationType) {
        String fullname = csf.getFullname();
        if (fullname != null) {
            File file = new File(csf.getFullname());
            FileObject fo = FileUtil.toFileObject(file);
            String url;
            try {
129             url = fo.getURL().toExternalForm();
            } catch (FileStateInvalidException ex) {
                /* Best guesses */
                if (Utilities.isWindows()) {
                    url = "file:/" + fo.getPath().replace(" ", "%20"); // NOI18N
                } else {
                    url = "file:" + fo.getPath(); // NOI18N
                }
            }

The root of the problem is that "fullname" is not correct:

fullname = (java.lang.String)G:/Documents and
Settings/nik/MP1//usr/lib/gcc/i686-pc-cygwin/3.4.4/include/c++/iostream

As a result "file" is also not correct:

file = (java.io.File)G:\Documents and
Settings\nik\MP1\usr\lib\gcc\i686-pc-cygwin\3.4.4\include\c++\iostream

And obviously "fo" becomes "null":

fo = null

I don't know how fullname got this strange value. This is a sample MP1 project. 
I set several "toggle" breakpoints inside main() and "function" breakpoint 
on main(); then I start debugging and press "Continue" 1 or 2 times, and 
NPE happens.
