The jvmti.xml defines the variable "onedotmicroversion" value using the SCCS %I% keyword:
<specification label="JVM(TM) Tool Interface"
        majorversion="1"
        minorversion="1"
        onedotmicroversion="%I%">

There are the following dependencies on the onedotmicroversion value:
jvmtiLib.xsl:
  <xsl:variable name="microversionbase" select="100"/>

  <xsl:template name="microversion">
    <xsl:variable name="micro" select="substring-after(//specification/@onedotmicroversion, '1.')"/>
    <xsl:choose>
      <xsl:when test="string($micro)=''">
        <xsl:text>dev</xsl:text>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="$micro - $microversionbase"/>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>

All the above needs to be fixed to complete a transition from TeamWare to Mercurial.
