Error [JBAS012144] when using jboss-as-maven-plugin to do remote auto-deployment

Issue

We are using jboss-as-maven-plugin to do remote deployment.
The example of plugin configuration snippet:

<build>
    <plugins>
        <plugin>
            <groupId>org.jboss.as.plugins</groupId>
            <artifactId>jboss-as-maven-plugin</artifactId>
            <version>7.5.Final</version>
            <executions>
                <execution>
                    <phase>install</phase>
                    <goals>
                        <goal>deploy</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                ...
            </configuration>

Sometimes we are getting JBAS012144 errors:
