Section 2.1.1. Important Notes on ZIP/Installer Installation Patching says that "the patching system cripples the original JAR files for security reasons." This is no longer true in EAP 7 as compared to EAP 6.

So, please remove this piece of text:

and the patching system cripples the original JAR files for security reasons. If the patch is rolled back, the original files will be reverted back to a usable state. This also means that the proper rollback procedure must be used to roll back any applied patch.
