json-smart should not package the asm classes

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a project with asm-1.0.2.jar and asm-5.0.1.jar on the classpath.
2. This will cause an issue with the classpath if asm1.0.2.jar is listed 1st 
because it bundles an older API. 

What is the expected output? What do you see instead?

I expect my app to continue running instead I get the following stacktrace:

What version of the product are you using? On what operating system?

asm-1.0.2

Please provide any additional information below.

Here is you can see that there was a change from the old asm code to the new.:

From looking at the pom, it seems you all are trying to create an OSGi bundle 
with a private package, however this jar can't be used in normal java if the 
never asm is also pulled i by transitive dependencies.  The correct thing to do 
would be to 

1.) Not bundle the asm classes and instead use package imports
2.) Create a your jar under your own name not asm-xxxx.jar because that name 
belongs to someone else and create a separate osgi bundle with the embedded 
class if you really, REALLY have to go the embedded route.
3.) Embeded the asm-3.3.1.jar in your jar and make sure to list the embedded 
jar in your Bundle-Classpath header.

I under stand the desire to have only 1 thing for a user to install, but it's a 
lie to say you don't have external dependencies and right now this setup causes 
real issues.

I second that request. You cannot use json-smart in combination with EasyMock 
3.3 because of the same issue. The ASM developers suggest to repackage the ASM 
code within a separate namespace (see http://asm.ow2.org/doc/faq.html#Q15).

interesting...

I may change this pakage name that look to be too generic...

asm is now renamed to accessors-smart

I get the same problem when using it together with GWT. asm-1.0.2.jar 
repackages the org.objectweb.asm classes. It conflicts with asm-5.0.3.jar. 
Could you remove these clases and use external asm instead?

It would be nice to have a new version.

Thanks!
