Distribution of EAP5 contains three files wstx.jar.
They are placed in following structure:
Files in client and lib directory are equal. The file in jbossxts.sar archive is totally different.
+ It misses any information about version!
I think that the customer could be confused by the fact that he has two files with the same name with totally different content.
The wstx.jar file inside of the jbossxts.sar should be renamed and correctly versioned.
