Whitespace before JVM argument prevents JBoss from starting

Issue

If I have white-space before a JVM argument in my host.xml's <jvm-options>, JBoss does not start and I receive the error message below.

<server name="server-one" group="main-server-group">
  <jvm name="default">
    <jvm-options>
      <option value="   -XX:HeapDumpPath=/tmp/"/>
    </jvm-options>
  </jvm>
</server>
