             Summary: When host jvm name and server jvm name are same then the host jvm settings are ignored
                 Key: WFCORE-665
                 URL: https://issues.jboss.org/browse/WFCORE-665
             Project: WildFly Core
          Issue Type: Bug
          Components: Domain Management
    Affects Versions: 1.0.0.Beta5
         Environment: All
            Reporter: Jay Kumar SenSharma
            Assignee: Brian Stansberry


- If the "host.xml" has the following JVM name defined 

{code}
    <jvms>
        <jvm name="default">
            <heap size="200m" max-size="2000m"/>
            <permgen size="256m" max-size="256m"/>
            <jvm-options>
                <option value="-server"/>
            </jvm-options>
        </jvm>
        <jvm name="Test">
            <heap size="300m" max-size="2500m"/>
            <permgen size="128m" max-size="128m"/>
        </jvm>
    </jvms>
{code}

- If the server refers to the above JVM name as following:

{code}
    <servers>
        <server name="server-one" group="main-server-group" auto-start="true">
        <jvm name="Test"/>
        </server>
    </servers>
{code}

- In above case when the server-one is booted that time  it takes the value from "server-group" (in this case main-server-group) defined in the domain.xml

{code}
    <server-groups>
        <server-group name="main-server-group" profile="full">
            <jvm name="default">
                <heap size="64m" max-size="512m"/>
            </jvm>
{code}

So the JVM settings defined for JVM name "Test" is overridden by server-group values:

{code}
30201 jboss-modules.jar -agentpath:/usr/lib64/libabrt-java-connector.so=abrt=on -D[Server:server-one] -XX:PermSize=128m -XX:MaxPermSize=128m -Xms64m -Xmx512m -Djava.awt.headless=true -Djava.net.preferIPv4Stack=true -Djboss.home.dir=/wildfly-9.0.0.CR1-SNAPSHOT -Djboss.modules.system.pkgs=org.jboss.byteman -Djboss.server.log.dir=/wildfly-9.0.0.CR1-SNAPSHOT/domain/servers/server-one/log -Djboss.server.temp.dir=/wildfly-9.0.0.CR1-SNAPSHOT/domain/servers/server-one/tmp -Djboss.server.data.dir=/wildfly-9.0.0.CR1-SNAPSHOT/domain/servers/server-one/data -Dlogging.configuration=file:/wildfly-9.0.0.CR1-SNAPSHOT/domain/servers/server-one/data/logging.properties
{code}

*NOTICE* the JVM runtime value is  -Xms64m -Xmx512m, where as it was supposed to be -Xms300m -Xmx2500m   as that is the "Test" jvm setting.
