----------------------------------

             Summary: module.path cannot be modified after it is set
                 Key: WFCORE-3895
                 URL: https://issues.jboss.org/browse/WFCORE-3895
             Project: WildFly Core
          Issue Type: Bug
          Components: Modules
    Affects Versions: 5.0.0.Beta5
            Reporter: Erich Duda
            Assignee: David Lloyd
            Priority: Blocker


*Scenario:*
* Run CLI in non-modular class loading mode.
* Run embed-server with {{--jboss-home}} pointing to server A
* Stop embed-server
* Remove server A
* Run embed-server with {{--jboss-home}} pointing to server B

*Expectation:* embed-server with {{--jboss-home}} pointing to server B will boot.

*Reality*: The following error message is thrown. As you can see the embed server tries to load modules from server A directory even if the jboss-home was set to server B.

{code}
Cannot start embedded server: The first directory of the specified module path /home/eduda/Projects/wildfly/dist/target/wildfly-A/modules is invalid or does not exist.
{code}

*Users impact:* Behavior of non-modular class loading \[1\] has changed. This change can break user's automation or tests.

*Blocker priority* was chosen because this is change in behavior against Wildfly 12.

*Technical details*

When the embed-server is started for the second time, following warning is logged.

{code}
2018-05-28 08:10:57,621 WARN  [org.jboss.as.embedded] (main) WFLYEMB0145: The module loader has already been configured. Changing the module.path property will have no effect
{code}

It seems that the change in behavior was caused by commit \[2\].
