problem

An application that contains both zk-8.5.0.jar and zpoi-3.9.7.jar, but ZK loads zpoi-3.9.7.jar/metainfo/zk/build, therefore show the error message:

Failed to process
Your ZK binary is being altered and may not work as expected. Please contact us at [email protected] for assistance.: Error:4665b2bef

Steps to Reproduce

1. set breakpoint in AbstractWebApp.loadBuild()
2. change path's value to "file:/Users/hawk/zk-1app/WEB-INF/lib/zpoi-3.9.7.jar!/metainfo/zk/build"

Current Result

a zpoi.jar path passes the check, so ZK will load zpoi.jar's build instead of zk.jar
"file:/Users/hawk/zk-1app/WEB-INF/lib/zpoi-3.9.7.jar!/metainfo/zk/build".matches("(.)zk-\\d.\\.jar
!/metainfo/zk/build") returns true

Since class loader doesn't return an Enumeration with a fixed order in different OS, sometimes zpoi.jar is the first object we visit in the loop.

Expected Result

not load build in zpoi.jar

Debug Info

• customer's environment wildfly 10.0.0.CR5

Root Cause

• in (.)zk-\\d.\\.jar
  !/metainfo/zk/build, the dot . after \d is the root cause

Workaround

• remove zpoi.jar/metainfo/zk/build
