           Summary: ClassNotFoundException loading applet
           Product: IcedTea
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: IcedTea
        AssignedTo: unassigned at icedtea.classpath.org
        ReportedBy: agajania at cs.newpaltz.edu


My platform is CentOS 5.2 with OpenJDK b11 from EPEL.

When loading an applet, the following messages are output:

netx: Initialization Error: Could not initialize applet.
(java.lang.ClassNotFoundException osp.OSP)
netx: Initialization Error: Could not initialize applet.
(java.lang.ClassNotFoundException osp.OSP)


Help in resolving this would be sincerely appreciated.
