Probably a Xalan bug. Try out something in the lines of

  <xsl:key name="hex" match="replace" use="from"/>
  <xsl:template name="js:escape">
    <xsl:param name="text"/>
    <xsl:for-each select="document('replace.xml')">
      <xsl:call-template name="js:escape.recursion">
        <xsl:with-param name="text" select="$text"/>
      </xsl:call-template>
    </xsl:for-each>
  </xsl:template>
  <xsl:template name="js:escape.recursion">
    <xsl:param name="text"/>
    <xsl:choose>
      <xsl:when test="not($text)"/>
      <xsl:when test="key('hex', substring($text, 1, 1))">
        <xsl:value-of select="key('hex', substring($text, 1, 1))/to"/>
        <xsl:call-template name="js:escape.recursion">
          <xsl:with-param name="text" select="substring($text, 2)"/>
        </xsl:call-template>
      </xsl:when>
      <xsl:otherwise>
        <xsl:value-of select="substring($text, 1, 1)"/>
        <xsl:call-template name="js:escape.recursion">
          <xsl:with-param name="text" select="substring($text, 2)"/>
        </xsl:call-template>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>
