customer is running an applet via a file url from a jar
file with a pathname that includes a space character.
when they open an input stream from a url made up of
the codebase (getDocumentBase()) & a filename, the URL's
openStream() method throws an AccessControlException.

this only happens with the 1.4.0 plugin - 1.3.1 was ok.

to test this, try running the applet at:

file:/net/kelvin.uk/export/dts/calls/417972/space dir/jdk14bug.htm

N/A

Too late for Hopper.  Committing to Mantis.

I was not able to reproduce this problem using my own (local) example.  Spaces in the directory names seem to work fine with jre 1.4.0 and 1.4.1
When I used example specified by the submitter, I got the exception.  I looked at the directory, and found that the directory is linked to itself (so "space dir" has a softlink called "space dir" that is linked to itself.  Why is it there?  Could you please remove it and try running applet.  I believe that it will work just fine.  Please update the bug with your findings.

Submitter removed the softlink from the example.  I run test case again and verified that there are no exceptions now in the Java Console.  Submitter is currently on vacation.  I will wait untill he can verify that removal of softlink fixes the problem before closing the bug as "user error".

The exception is still thrown in Java Console.  I tried running the applet through appletviewer.  The same exceptions that are trown in Java Console are thrown in korn shell window if I am running the jdk14bug.htm with appletviewer 1.4.1  These exceptions do not occur in appletviewer from jdk1.3.1.  I have two more examples of applets that have spaces in their paths, but there are no exceptions while running those applets with either jdk1.4.1 or 1.3.1 - one of the differences that I see between my examples and submitter's is that submitter's example is reading a string from a text file to be displayed inside applet's box.
This does not look like plug-in bug, since it is reproducible with appletviewer.

Looks like this bug is a duplicate of 4697178.  Fix for bug 4697178 is planned for hopper.
