Global Variable / Extension Function Bug

[Cole, Kristopher A. (LNG-DAY)]

I'm running into a bug when I have a global variable, that has another
variable nested within it, that is called by a Java Extension Function.

For some reason, when this happens the last global variable takes on the
value of the nested variable above.

For example, in the document below the output would be "Real output Should
not be output".
The java function is irrelevant.  In this case it is as simple as returning
the value it is passed.

This seems to occur with multiple versions of Xalan, but I'm using 2.4.1.
There is an obvious work-around of not nesting variables in global
variables, but I'd like to understand why this is happening.

Here's my example stylesheet:
<?xml version='1.0'?>
<xsl:stylesheet version="1.0" 
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  xmlns:toolPackage="xalan://tools">

  <xsl:variable name="gVar1">
    <xsl:variable name="lVar1" select="' Should not be output'"/>
    <xsl:value-of select="'Data for java function'"/>
  </xsl:variable>

  <xsl:variable name="gVar2">
    <xsl:value-of select="'Real output'"/>
  </xsl:variable>

<xsl:template match="/">
        <xsl:value-of select="$gVar2"/>
        <xsl:variable name="lJava"
select="toolPackage:Test.TestString($gVar1)"/>
        <xsl:value-of select="$gVar2"/>
</xsl:template>
</xsl:stylesheet>

Thank you.
