[jboss-jira] [JBoss JIRA] (WFCORE-2223) Setting JBOSS_MODULEPATH is lost for second start of embed-server

[Brian Stansberry (JIRA)]

    [ https://issues.jboss.org/browse/WFCORE-2223?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13353009#comment-13353009 ] 

Brian Stansberry commented on WFCORE-2223:
------------------------------------------

See "Modular vs Non-Modular Classloading and JBOSS_HOME" in http://wildfly.org/news/2015/03/13/Offline-CLI/ re module loading. Basically if you run the CLI as a modular application, the module path is what was used to set up the CLI process, and if you use jboss-cli.sh it supports JBOSS_MODULE_PATH. If you do not run the CLI as a modular app, then the module path is <value_of_jboss_home>/modules and JBOSS_MODULE_PATH has no meaning.

The simple thing to do here is to remove the validation of the property value. The property is deprecated and has had no meaning for many years; all it does is drive the value of a deprecated runtime management attribute that we preserve for management API compatibility. There's no reason to validate this value.

> When {{embed-server}} command is used more times in the CLI and a custom {{JBOSS_MODULEPATH}} is configured, then only the first server start uses the correct module path.
> The subsequent `embed-server` call results in error:
> {code}
> Cannot start embedded server: WFLYEMB0022: Cannot invoke 'start' on embedded process: WFLYSRV0118: Determined modules directory does not exist: /tmp/jboss-eap-7.0-no-modules/modules
> {code}
> Using the  {{JBOSS_MODULEPATH}} environment variable is documented in https://access.redhat.com/documentation/en/red-hat-jboss-enterprise-application-platform/7.0/single/configuration-guide/#define_an_external_jboss_eap_module_directory
