             Bug #: 854
           Summary: Resizing an applet several times causes 100% CPU load
    Classification: Unclassified
           Product: IcedTea-Web
           Version: 1.1.3
          Platform: x86_64
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Plugin
        AssignedTo: dbhole at redhat.com
        ReportedBy: peter at morch.com

http://morch.com/download/openjdk-icedtea-hang/ demonstrates how resizing an
applet from javascript cause 100% CPU usage indefinitely. I.e. the applet

The reproducible steps I took to reproduce this:

* Boot from xubuntu-11.10-desktop-i386.iso LiveDVD
* sudo apt-get install icedtea-plugin
* Start Firefox
* Visit http://morch.com/download/openjdk-icedtea-hang/
* Open top in a terminal
* See that java takes up 100% CPU

See demo at http://morch.com/download/openjdk-icedtea-hang/ and
https://gist.github.com/1621288 for index.html and the applet's source (55
lines in all)

I'm not sure whether this should be reported against OpenJDK, but then I hope
you'll let me know! :-)
