Cannot discover classes using OneJar

[GoogleCodeExporter]

I wouldn't call this a bug, but figure it might be useful. I found a few 
questions online alluding to trying this, but did not find a solution. 
Hopefully I didn't reinvent the wheel here ... 

What steps will reproduce the problem?
1. Package application using One-Jar (one-jar.sourceforge.net)
2. reflections.getSubTypesOf(<your class>; presumably this impacts all types of 
discovery
3. Run application.

Returns no values when using the One-Jar classloader. The default classloader 
returns results as expected.

One-Jar v.97
Reflections .9.8
OS: Windows 7 x64
Java: 1.6.0-b105

Solution: Custom UrlType and custom Vfs.Dir; attached. Uses OneJarURLConnection 
to correctly read content from embedded JARs; uses 'standard' Vfs.File.

(The Vfs.UrlType.matches(..) may conflict with the existing implementation 
JarUrlType if both are added to the available UrlTypes.)

I'm attempting to address the same issue in one of my projects.  After 
incorporating the OneJar*.java into the project and registering the 
OneJarUrlType with Vfs using addDefaultUrlTypes I was still not able to 
discover classes in the packaged jars. I'm using 1.6.0_xx under Windows 7 64 
bit, and OneJar 0.97.  The embedded jars are visible as resources but not 
navigable from any entrypoint I've tried so far.

Am I missing a step?

Update - by using ClasspathHelper.forClass(SpecificSuperClass.class) I was able 
to find the classes in question; any other class path helper specific to a 
loader met with the same (null) results.

I'm not sure why that's the only method that would work; but that's always
the method I use. The implementation, as you can see, should not be
specific to a particular helper or implementation.

I hope it still proved helpful!
