RE: [eclipselink-dev] Unexpected AssertError - cannot reproduce - c:/dir with spaces/META-INF/persistence.xml resolves fine in windows 
Ok, outside of eclipse entirely, I created a directory called "c:\My Demo"
and created MyDemo.java as follows:

import java.io.File;
import java.net.MalformedURLException;
import java.net.URL;

public class MyDemo {

    public MyDemo() {
	URL url = null;
        ClassLoader loader = this.getClass().getClassLoader();
        url = loader.getResource("MyDemo.java");
        File f = new File(url.getFile());
        System.out.println("Result = " + f.isFile());
    }

    public static void main(String[] argv) {
	new MyDemo();	
    }

}

This is similar to the check done with the AsserError. I compiled and ran it
from the command prompt, and got

Result = false

When I rename the parent directory to "c:\MyDemo" (no space), I get:

Result = true

So, it appears that isFile() doesn't like the %20 that the getResource(...)
call is returning. This is using JDK 1.6.0_06 a Vista computer and on an XP
computer running JDK 1.6.0-b105. Note that both are on a domain, and have a
couple of mounted network drives (if that by chance makes any difference). 

Does this help?

John,
	Hi, could I ask that you zip up your Eclipse project or a test
project that reproduces your problem.
	Since we are both running Vista on JDK6, we will import your project
and see if we can get the same problem here.
	I am running Ganymede 3.4M5, I have a 3.3 europa version - let us
know which eclipse version you are running.
	
	thank you
	/michael

Also, for what it's worth, I'm getting this exception on Vista.

John,
	Hi, I would like to work with you to resolve this issue, but I
cannot at this time reproduce it on windows - this test scenario still
passes, I will try jdk6_u10.

	1)	I ran one of my original test cases that matches the
scenario of users that are constrained to create eclipse projects off their
c:/documents and settings/ directory.  I am unable to reproduce your error.
I work fine with a space in the file path of a J2SE JPA eclipse project.
		The error that this original 2008/03 fix addressed was based
on a key:value mismatch on %20 vs " " - you have a different scenario that
is earlier in the code path.

-----------------ReTesting Output--------------------- See attached jpg for
a view of the eclipse test project

	2)	I also unit tested the code outside of EclipseLink in line
137 aFile.isFile() returns true for a file at the end of a file://dir with
spaces/ url
		The only way I could get the following code to fail is if
the xml file did not exist.

            URL pxmlURL = new URL("file://c:/_testing/space
dir/META-INF/persistence.xml");
            File aFile = new File(pxmlURL.getFile()); 
            assert(aFile.isFile());            

	Your error bothers me, if you have any more specific info on your
setup like your OS (linux or windows), the path to your persistence.xml and
if you are running inside eclipse as a SE run target it would be helpful in
fixing your issue.

	thank you
	/michael

Hello John,
   There is a pre-existing bug 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=210280 which was fixed for 
jars but based on your report seems to be still broken for files.
Could you please reopen the bug and post your new findings.
Thank you,
--Gordon
