Bug 42435

The method DefaultErrorHandler.javacError(JavacErrorDetail[]) contains the
following code:

    for (int i=0; i < details.length; i++) {
        if (details[i].getJspBeginLineNumber() >= 0) {
             ...
        }
    }

Basically, this means, that error details are skipped, if the line number is -1.
Unfortunately, there are cases, when the compiler reports events with -1.

I propose, to change this code to look like in jasper 6:

        for (int i=0; i < details.length; i++) {
            if (details[i].getJspBeginLineNumber() >= 0) {
                args = new Object[] {
                        new Integer(details[i].getJspBeginLineNumber()), 
                        details[i].getJspFileName() };
                buf.append(Localizer.getMessage("jsp.error.single.line.number",
                        args));
                buf.append("\n"); 
            }
            
            buf.append(
                    Localizer.getMessage("jsp.error.corresponding.servlet"));
            buf.append(details[i].getErrorMessage());
            buf.append("\n\n");
        }
