I cannot confirm that. In real live, with Java apps not developed
for OpenJava, 50% of the "large" applets as developed using Sun
JDK fail with OpenJava. A simple example: The german tax office
has an online tax system called "Elster". There is an applet
for secure communication with Elster using public/private
keys, this applet fails using OpenJava. Another example is related
to javax.imageio, output of images to files simply does not work
in OpenJava. Installation of Sun Java is one of the first modifications
I do to Fedora. Unfortunately, on every update of OpenJava, OpenJava
would become the default Java again.
M$ has given the freedom of selecting between IE, Firefox, Opera etc.
It would be a good act of freedom to give the fedora user the choice
between OpenJava and SunJava. At now, half the Fedora System depends
on OpenJava (same story as of Windows depends on IE), for that reason
I cannot deselect OpenJava.
