While OpenJDK is mostly the same codebase as the proprietary Oracle JDK
(and, in fact, is the reference JDK for 7), the plugin and javaws are
not part of OpenJDK.  Sun never released the source code for these
and they aren't part of the compatibility test suite (TCK).

The packages in Fedora and other distros are thus an independent implementation
developed primarily by developers at Red Hat in a project called IcedTea-Web:

Fixing incompatibilities between this and the proprietary implementation is
a matter of finding issues and doing our best to fix them.  In this, the
help of users is of great importance and we'd appreciate bug reports at, with as many details as possible.

As Andrew Haley implies, there are some issues where we can't reproduce the
fault.  Your case would appear to be one of them, as we would not have a
username and password to enter into the app.  This is also true of many
banking sites.
