           Summary: Applet does not render graph using IcedTea; works on Sun
           Product: IcedTea
           Version: unspecified
          Platform: PC
               URL: http://www.rahastot.fi/en/
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: IcedTea
        AssignedTo: unassigned at icedtea.classpath.org
        ReportedBy: sami.makinen at helsinki.fi

Rahastot.fi is a stock fund information service. For each fund, a graph of
historical values is rendered as an applet. Why an applet is used remains a
mystery, where a simple fully server-side caching image rendering service could
be used instead. The Sun JRE renders the graph as expected on 32 bit systems,
but icedtea-gcjwebplugin 1.0-0ubunt on a 64 bit Kubuntu 8.04 on Firefox 3 does
not render the graph data. Instead it only renders a blank graph grid with axis

Steps to repeat:
1: go to http://www.rahastot.fi/en/
2: click any fund name -> new tab opens
3: scroll down to applet, just before "Show performance" dropdown with time
ranges in it

Actual results:
Graph does not have any content

Expected function:
Applet should render a graph line and/or fill

I can't follow my stock on my desktop, and have to use my laptop instead! While
this isn't a life or death issue, it sure would be nice if it worked.

The graph applet is in an iframe, so before anything else right-click near the
graph and choose "This frame" > "Show only this frame" to isolate the applet.
Then check the page sources - the graph data seems to be in a Very Long set of
applet parameters. Some values from parameters are definitely parsed
successfully, e.g. <param name=yAxisStart value="91"> and
<param name=yAxisEnd value="103"> - these are rendered next to the axis as
expected. Perhaps the problem lies in parsing parameter values that have
linefeeds in them? The markup defining the applet seems ok to me, except that
<param> tags are not terminated, but that shouldn't be the problem because the
axis values are parsed successfully.
