Converter icons in metadata results are not displayed (only 2.9.x)

[josegar74]

This is related to spring security changes, seem this code in metadata-utils.xsl:

<xsl:for-each select="/root/gui/schemalist/name[text()=$schema]/conversions/converter">
  <xsl:variable name="serviceName" select="@name"/>
      <xsl:if test="java:isAccessibleService($serviceName)">

sends a node tree object to isAccessibleService instead of the string value with service name.

Changing serviceName variable to:

 <xsl:variable name="serviceName" select="concat('',@name)"/>

solves the issue
